UE5.2 Crash whenever I place foliage in certain places.

Hey, I am working on an environment for my game and my editor immediately crashes whenever I place foliage on terrain in most parts of the map. I have world partition enabled.

Here is the error from the crash:

Assertion failed: !IsValidChecked(ExistingActor) [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\ActorPartition\ActorPartitionSubsystem.cpp] [Line: 280]

If anyone knows what could fix this I’d be greatly appreciative, this issue is basically blocking me from making my environment right now.
