what is destroying cores out of thin air

[Mythr]

I was playing Foundries and Forges in Pure Survival mode earlier today with my squire. In the middle of wave 14 the crystal took damage when absolutely nothing was around it. I had sealed off all the spawns at the bottom and didn't have any towers up top that could have taken out anything that actually was up top hitting the crystal, so if there was something, it should have stuck around and kept hitting it. I ran up and checked. Nothing there. I was the host, so I know it wasn't a network issue.

its highly possible a kobold run straight through your walls. it happens quite often out of nowhere, on every map. i use EV walls almost exclusively in my builds because they are just better bang for the buck, but i have seen kobolds on glitter survival run straight through them like they werent even there. ive also see walls go from full to less than 60% health in an instant on magus quarters survival, usually between waves 14 and 17. it happens at least once per run. i assumed that was just the reflect wall bug kicking in though.

another bug with reflect walls, which i think is more likely your culprit in this instance, and i see this happen all the time, especially with djinn, but bolts and fireballs and other things will fly right through a reflect wall.

without knowing your build and how you are placing things, one other thing i have seen happen many times is if you place your walls/reflect walls directly at the top of the stairs that lead to the crystal platform, and you have them on the raised border of the stairs or the walkway, there will be a gap between the walkway and the bottom of your wall that arrows/fireballs/whatever can and will slip through and hit your crystal.

Happened to me tonight doin MM NM HC on Jungle wave 14 sailin along for a "good monkey" and the crystal imploded for no reason. The only enemies in the area were kobolds and mages, but i had a darknes, proxi, gas, ensnare, physical wall, and a reflect bc it happened on the same crystal before so I added the reflect(all those towers were boosted also). Im not mad bc I lost, but I am confused as to how to improve my build if I dont know what and why? I agree about the stat bein posted idea and idk how anything coulda made it through all the towers i had laid down, I guess I wont be doin MM untill they fix that on that particular map.

I was playing Jungly NMHCSV and crystal was destroyed on wave 13-14, but end view showed that nothing was attacking it. There was proximity trap nearby which should have killed smaller enemies.

I think there is a rare glitch involved, but it does seem pretty unpredictable. Most of the time it's just random shots from ranged attackers that manage to drift through at a perfect angle, which of course isn't a bug, just really odd luck.

But for some people that pile a lot of defenses very close to the crystal, I think that occasionally the game suddenly thinks the crystal is underneath something and takes damage from it. It shouldn't happen, and only happens like every 1000th crystal rotation. Totally unconfirmed, and doesn't help explain what happens to people that don't use any defenses near their crystal.

Also, for people that mention they have completely protected their crystal with reflect beams. You have to be sure that they overlap because if they don't overlap, then you have a gap that the ranged shots can pass through.

I had sealed off the spawn points with harpoons and bowling balls. There was no path for a kobold to take without destroying one of my towers, which didn't happen. If things are randomly deciding to go into non clipping mode and ignore all defenses, it would have some pretty serious implications for a tower defense game. I also don't think it can be a projectile, as it would also have to go through several of the level's walls to get to the crystal from the spawn.

ok this happpen to me everytime i try to solo glitts and alt-tab, if this happening to you when u playing solo, is the afk protection or some like. If ur active on game or there is other players then the reason could be the dark magues (healers) throwing fire balls directly to core and in survival high waves they can 2 or 1 hit kill the core like np. This happened to me on mm till i found a place to set harpons and kill those magues which were stuck on a corner and not getting dmg from harpoons. To fix that u set reflect walls directly in the core (2 DU). IF u do that and is still happening is probably a bug but try that

This happens to me reliably on The Throne Room Insane Mixed Mode Survival, right around wave 23 or so.

I've tried a bunch of different setups, including completely surrounding the front core (the one that always dies) with overlapping reflective barriers.

I did notice something, on two separate occasions, though.

Specifically: There was a mass of wyverns right by one of the doors, I was shooting at them with my monk, and my buddy was standing on the crystal with no mobs around him... one of the wyverns went UP into the ceiling, and IMMEDIATELY afterwards my buddy died and then the crystal died.

And every time I was paying attention when it happened, there was a bunch of mobs and wyverns were coming out.

It really looks to me like wyverns are getting pushed outside the normal confines of the level, and then they kill the crystal unstoppably.

Whyverns shooting a fireball at you, dying then the fireball hits the crystal

it happened to me last night in a group i was running city in the cliffs with. i was protecting the west crystal and on wave 14 the swarm of wyverns, that i was doing a relatively good job keeping under control, one of them managed to destroy the crystal when i had my back turned to it. i was alternating the left and right wyvern spawns, and when i was dealing with the left, the core exploded. the only thing i can assume happened was the wyvern launched a fireball and that did it in.
