I tried to disable Faeries and Willothewisps via the config file by setting them to false, but I am still seeing them generate in worlds. I have 1.12.2 and the 0.4.1 lumen and forge b2805. I have other mods, including biomes o plenty, but I'm not sure what would be causing this to ignore the config file. There's no crash log or anything in the launch log about it.

This must be an incompatibility with some other mod, since I make sure they work every time I publish a new update. Also, sorry, but since development and support has stopped for the 1.12 version, I won't investigate this issue further.
