Hydras and scylla in the campaign don’t spawn new heads until they reach the maximum damage needed to spawn all 5 heads. After which they suddenly gain 5 heads.
Trigger Event:
It happens a few missions in the campaign. I haven’t tested if it affects skirmish. Other users suspect that mods might have something to do with it, but have confirmed that turning them off had no effect.
Noticed this bug too yesterday on mission 4.
The heads will all spawn suddenly when the hydra reaches it’s fifth head. Meanwhile, it will remain at “level 1”, dealing weak damage.
Noticed this bug too yesterday and today when I was playing in Skirmish, I was playing with mods but none of them mess with Hydras or Skyllas. Tried without mods but still didnt work.
