Subject: [PATCH] Fix swamp hut cat generation deadlock
|
|
|
|
The worldgen thread will attempt to get structure references
|
|
via the world's getChunkAt method, which is fine if the gen is
|
|
not cancelled - but if the chunk was unloaded, the call will block
|
|
indefinitely. Instead of using the world state, we use the already
|
|
supplied ServerLevelAccessor which will always have the chunk available.
