I've found this issue when building an underground base, the skeletons keep spawning even when (according to more overlays and f3) the light level is always above 7. This happens in a mycelium biome (where they also spawn against mycelium biome spawn restrictions (pretty sure giants also spawn there)

Updated the server to v. 0.5.1 Didnt make a difference

Thanks so much, I'll have a look out!

Thanks, I found what was causing this and in the next update it will be fixed :)
