Luchs Arcana

I have been refered to here to report this bug, I hope this is the right place. How to replicate the bug: Open a new forge version, no mods, minecraft 1.21.5, forge 55.0.4 and lower, place/find warped nyleum, try to place a warped fungus. The problem: the warped fungus cannot be placed. What I expect to happen: The warped fungus should be placeable on warped nyleum, otherwise the big fungi cannot be grown anymore.
