ConcurrentModificationException #399

Closed rajp33 closed 1 month ago

rajp33 commented 4 months ago

I believe a fix was put out a while ago for ConcurrentModificationExceptions being thrown. We still see some being thrown here and there. Don't have much to go off of besides a stacktrace though. Not able to consistently reproduce it

Default enforce is non-thread-safe, you can switch to SyncedEnforcer, or you add a loading request to the single thread to avoid the concurrent issue.
