Fawe Debugpaste

debugpaste is not working so here is my log: https://paste.gg/p/anonymous/b5abd4a969ef4870ab702697209c8d52

Fawe Version

FastAsyncWorldEdit version 2.6.3-SNAPSHOT (https://ci.athion.net/job/FAWE-PS-v7/)

Checklist

I have included a Fawe debugpaste.
I am using the newest build from https://ci.athion.net/job/FastAsyncWorldEdit/ and the issue still persists.

Anything else?

This stacktrace was reported in #2131 (comment) but there is still no proper way to reproduce it I guess.

This ConsoleSpamFix does make me wonder if it hides something we need to know in order to find the cause. Would be better to get rid of it at the moment and the builder retries what he did on your server

OneLiteFeather · Answer 3 · 2023-06-13T18:15:42.000Z

Also how is it possible that the /fawe debugpaste command is not working? Can you retry that as well?

OneLiteFeather · Answer 4 · 2023-06-19T14:44:31.000Z

Here you go, important to reproduce (like it happened in the wild) is to undo someone else quite a few times after the person left

That was 1.19.4 with fawe-473
