Wizardry Challenge & Djinnlet pet

[Bull]

I was trying to do the wizardry challenge with the layout from the forums and figured the proximity mines are a great idea and will do the thing in a blitz but I noticed that the vulnerable wizard ISN'T damaged by the mine at all. Is this intended? The last wiz on first wave was standing directly on my proxi and I was injuring it with my weapon and the proxi was detonating all the time but it didn't damage the wiz at all.

Another bug I've noticed is that the djinnlet pet with it's elemental attacks doesn't attack with it's elemental attack v monsters with the resist to the element even after the affinity has been removed by the monk aura or the darkness trap. That's 1/3 of it's damage potential gone and if it's a low level pet, it might not attack at all (if it has only 1 projectile).

The wizards on that challenge are not vulnerable to tower damage. It's intended.
