What happened?

This issue is the same issue as #1346

From my understanding this an issue with the Vampirism mod itself and how it handles the Vulnerable Remains health check.

Basically at the beginning of the crash log we can see that Minecraft calls the demoteFullChunk function meaning a player has left the area and the chunk is about to be unloaded, this then further calls the onEntityLeaveLevel event which after a few calls needs to determine if the entity is alive or not for saving purposes and calls the VulnerableRemainsDummyEntity#getHealth function.

Due to the implementation of this Entity it has an associated Block Entity which is what stores the health and here is where we run into a problem. To get the Block Entity Minecraft first has to fetch the Chunk that the Block Entity is in which normally wouldn't be a problem however the code is trying to fetch the Chunk while the Chunk is being unloaded, therefore leading to the ConcurrentModificationException in question.

Fixing this would likely require a reimplementation of how the health is stored/accessed.

here's my log too.

For context, this is a new world (10-20 mins max), where I just became a hunter, became a forest dragon from dragon survival, upped the generation rate of vampire forests via terrablender, and I was just flying towards a vampire forest. I stopped to get some food, and (probably when I started moving away from the forest) my game crashed.

Thank you for reporting and already investigating the likely cause.

I can confirm. For me the crash happens quite reliable. Although the stacktrace is a bit different, it seems to be the same problem.
A test version shows that the tile entity actually tries to access the unloaded chunk. I am not sure why this usually does not happen. Maybe it is only Create that triggers this getHealth check during unload.

I think it should be sufficient to properly check whether the chunk is loaded before accessing the tile.

@Cheaterpaul
Maybe we should also add a check here

Vampirism/src/main/java/de/teamlapen/vampirism/blocks/mother/MotherTreeStructure.java

Line 69 in 8d884c0

if (!(blockState.getBlock() instanceof IRemainsBlock)) return Optional.empty();

to avoid loading new chunks when resolving the tree?

        visited.add(pos);
+        if(!level.hasChunkAt(pos)) return Optional.empty();
        BlockState blockState = level.getBlockState(pos);

Maybe also here:

Vampirism/src/main/java/de/teamlapen/vampirism/blocks/mother/MotherTreeStructure.java

Line 119 in 8d884c0

return getCachedVulnerabilities().stream().map(pos -> {
