Spiders bunching up in front of Defenses?

[Mustangg]

Earlier today I was soloing UMF without any issues using my squire. Now, all the spiders get bunched up in front of the barricades and the harpoons just shoot over their heads. This causes them to web up the harpoons, ogres break through, and then the round is over. Also, it seems to shoot right past the fliers into randomness.

I'm not exactly sure what happened but this needs to be looked at, since it was working great earlier.

They tried to make the harpoons smarter but only made them stupid.

harpoons can't shoot spiders when they are close to them!
Z axis colission of harps in now too high

TE completely screwed up the harpoon towers with the 7.17c patch.

Hopefully 7.17D will be a proper fix.
