An unrecognised crash: RejectedExecutionException in Exception in server tick loop
The crash report says it died in Exception in server tick loop. The exception is java.util.concurrent.RejectedExecutionException: event executor terminated. The topmost frame outside vanilla and loader code is io.netty.util.concurrent.SingleThreadEventExecutor.reject. No frame in the stack carries a mod annotation, so there is nothing to bisect from here: halve the pack instead, and bring the share link to our Discord.
