Yeah, this is something I'm looking at. It might even need to be longer - but I want to balance the Time to Kill on the high end Uniques first.
Hi Con ! I just had the same issue, 30 seconds before the end a bullet resistant unique elite with a mace or something like that spawned with the last wave (unidentified building, lv54), barely scratched it before the timer ran out. Had lot of freezes but I'm pretty sure it was explosive immune too because it wasn't knocked down when a grenade exploded at its feet.
I know it's hard to tune, keep the good work !
[EDIT] And another, at the end of a rush @18 seconds from the end.
