I think I'm having a similar issue. I updated the mod from 3.1 to 3.2 yesterday, and then upgraded my warp platform with Factory Upgrade 5 and Ground Upgrade 6. After which, I haven't seen any changes to the biters I'm facing in waves (I warped a few times to make sure). Checking the map panel and with the /evolution command, all my evolution factors start at 0.5, where I think they should be 0.7 now. I think the evolution scaling might be broken currently. And yeah, the tips and tricks entry for evolution scaling seems to be broken. It says: Unknown key: "tips-and-tricks-item-description.warptorio-evolution-scaling". Also, I don't see any big asteroids since I updated the mod, but I think that's an intended change.
