When RPLE is present I go and check the Thermal Dynamics Covers Tab in Creative and they don't appear even though when I highlight on them it says they're there.
The mods im using is RPLE (latest), unimixins, gtnhlib, CoFHCore, Thermal Dynamics, lwjgl3ify-2.1.14, falsetweaks, lumi, chunkapi, falsepatternlib.
