this bug happened in the wave with 1 level 360, 1 level 180, 1 level 90, 1 level 45 and 1 level 22. i killed the 90, the 45 and the 22. i made sure the lvl 180 got stuck behind the 360 so i could easily range the 360. well when i killed the 360 it respawned again :? and i didnt kill the 180 yet. it spawned on the same spot where the 360 died and i got 2hit 8)
