IDK if this is Tenebris or one of my other mods causing it to do this...

I think this is caused by incompatibilities, I've pushed out a potential fix, please give it another shot.

I've had a similar issue where the Bioluminescent Drill doesn't load/exist in the Lua.

This should be fixed.

I love the effort your putting towards the updates that error is gone now but I have a different one that's come up, I assume its other mods again but I figured I should toss it here just in case it was fixable.

Seems to be an issue with 2.0.20 release

I just updated to .20 and the mod failed to load

With only this mod enabled (along with Space Age of course):
