So i was making a nightmare biome for my nightmare dimension, when this error popped up:
C:\Pylo\MCreator155\forge\build\sources\java\mod\mcreator\mcreator_nightmareBiome.java:125: error: incompatible types
topBlock = mcreator_nightmare.block;
FAILURE: Build failed with an exception.

Could somebody please tell me how to fix this? D:
