only seeing original type of biter. no evolution of other biter types while playing

[DoomSquirter]

running full bob's mods and most angel mods but not angels exploration definately bobs enemies also combat mechanics overhaul

I swear I had this problem before a long while back but forget what I did to fix this

Basically, I'm at 30% evo and I've yet to see anything but normal biter bases

I'm seeing them use rampant tactics like grouping large groups into one entity and getting a number and rushing up to walls, etc

but it's all "base" biters all around me and nothing else

I searched through the mod portal page and saw some ppl having same issues but nobody responded to them.

So I'm at a loss

Any insight would be greatly appreciated.
