Crashlog examples

Essentially, the singleton here only gets called during a cast of EdifySapling, which is too late for the underlying registration at this line.

Adding the single line :
AkashicTreeGrower.INSTANCE
at FabricHexInitializer ln100 seems to fix it without any side effects for Fabric or Forge, though I can understand if that's a violation of the code style.

EDIT: I've got a branch with this modification and a bump to the Cardinal Components accepted versions here, if it would be easier to look at that way, though I can understand not wanting to deal with this as a PR.
