[CloudeLecaw]

i see your using 1.21.8 might it worth to use Images 2.5.7 here?

[bobhenl]

I already updated to latest and it's still happening @CloudeLecaw , I'm also crashing due to

[bobhenl]

yeah these two are related... it kicks client when this happens

[CloudeLecaw]

warum benutzt du die 2.5.8 welche für only 1.21.10 geschnitten ist?

Bitte nutze die Versiob 2.5.7 wenn nicht gar nur 2.5.6

[bobhenl]

But my server is right now 1.21.10, you can see it in the errors
purpur-1.21.10.jar

and I'm still getting that error with ver 2.5.8.j that's supposed to be for it. In the last error it's mentioned in stacktrace @CloudeLecaw

[CloudeLecaw]

you should give a try on paper as it was made for paper and spigot...to see if your error arrours there too and not for pupur

Dont say "but pupur is just a fork of...."
We both know that very often forks are not just optimized code things
so give it a try on paper because that seems to be closed to me to pupur.

If it works on paper 1.21.10 (like on our live server) then you know it simply doesnt support pupur (well it was written its only for spigot and paper anyway....So trying it on pupur at your own risk)

Might the dev finds a solution here for a fix, might not.. at the moment it looks like its not working with pupur.
so waiting for your results <3

by the way in this test it was not even pupur her it was leaf the fork of fork... so if it wasnt working allready on pupur so dont aspect a working on leaf..
