I was on the Windows build. I kind of figured the Insect Angels were intended, I just thought it was odd to call them Angels. But it probably makes Sense in your World.
I feared it could be the Windows build so I made some changes that should hopefully prevent the game from not granting any perk points every 3 levels.
Are you devving on Linux then?
Mainly Windows, hence the lack of testing for the now discontinued Linux version.
