[1.20.1 / Forge / 1.4.11] There is a very small chance of a crash between the Spore (Fungal Infection: Spore) mod and this mod (Dynamic Trees).

[XuasKey]

Environment:

Minecraft: 1.20.1
Forge: 47.4.20
Dynamic Trees: 1.20.1-1.4.11
Spore (Fungal Infection: Spore): 1.20.1_2.2.0j

I am experiencing a rare but fatal server crash when using the Fungal Infection: Spore mod alongside Dynamic Trees. The crash occurs when a Gargoyl entity from Spore uses its SmashStomp ability. During this ability, the mod attempts to retrieve the hardness of a block at the target position, which triggers TrunkShellBlock.getHardness() from Dynamic Trees. However, if the target block happens to be air (which can occur in some situations), the method proceeds to call getMuseDir() and assumes the block state has the coredir property, resulting in an IllegalArgumentException.

I am the person concerned. This issue was filed by someone else on my behalf at the time because the network environment made GitHub inaccessible. Now it's back to normal. This is a simple analysis of the crash cause from an amateur like me, which might help the author fix the bug.

Since I do not visit GitHub often, I may not reply to further follow-up questions directed at me. I would appreciate the understanding of the author or anyone else interested in this bug.
