We have been having performance issues for the past hour or so and it finally all came down. Screenshot by Lightshot
I believe I found the issue. Keep in mind these are chunks/entites for direwolf20 new (2) Screenshot by Lightshot
Seems like it is being looked into so be patient For future I'd suggest going to the Public Slack as it is much quicker to get a hold of someone especially for a situation like this.
It looks like somone fixed it with a manual reset but thanks for the feedback I'll be sure to use that next tine.
Couldn't find the location, issue is fixed until the specific player loads the chunk with the block again.
