So apparently I come back and see that the bosses can punch while being stunned... this does not affect players but it does buildings. The boss should NOT be able to destroy buildings while stunned.
There was a bug after the big update, jelly implemented a work around so he at least could not kill the players. I dont know if its fixed again now, jelly knows best.
the big update a few weeks ago broke alot of stuff, including all forms of stun on Hale (including vanilla stun, like Sandman) i have an idea for a fix and will try to implement it sometime today
I got about 7-8 telefrags last night... I just had to work around it... amazing how even regulars fell for it... no dispenser used either.
