When i try to play the dummy assault mission and trigger the enemy spawns the new enemy dummies attack they start digging into the ground and kill their brain. have anyone else got this problem?

Also im not sure where i should post this so i took a gamble and posted here.

I have gotten this problem before, TLB said it was due to AI settings in the mission or whatever.

Actually the rally point for some of the dummies is going to the brain chamber to guard it, unfortunately they get stuck and start digging, and when they get to the brain they continue holding the digger spraying everywhere, eventually killing it's own brain.

Anyway to fix it?

Find the part in the mission script where it tells the dummies' AI to go to the brain. Remove that.

It is one of the fixes in the Unofficial Cortex Command Patch, which might be simpler for you.

The brain will also occasionally detonate due to MOID exception, so sometimes it's not the dummies' digging which is directly responsible.
