    posted a message on Server crashes, seem to be related to players being near certain chunk

    Hey folks, we have an issue where the server crashes whenever we get near a certain area. I recently built a zero-tick bamboo farm in the area and may have accidentally ran out of storage, so it's just throwing an item out every second or so. We tried turning off the server watchdog, but it still crashes. We can't even teleport into the chunk. Any idea what's going on?


    Here's the crash report
