When I open a singleplayer world with this mod, I get the following error:

The game crashed whilst mouseclicked event handler
Error: java.lang.NoClassDefFoundError: com/sk89q/worldedit/session/SessionOwner
Exit Code: -1

I thought this might mean I need worldedit, so I downloaded the latest version, but now it's just a different error:

The game crashed whilst exception in server tick loop
Error: java.lang.NoSuchMethodError: net.minecraft.class_5455.method_30530(Lnet/minecraft/class_5321;)Lnet/minecraft/class_2385;
Exit Code: -1

Did you used the stable release from curseforge? Or the experimental 21w10a release from worldedits build site (thats the only worldedit release in existance, that works with dimdoors 21w11a)?

and no, as far as I know this solution is written nowhere.. I had to do some digging until I found it.

do you have any links to this? the new version for 21w15a makes the 2nd error as seen earlier.

Ah fantastic.. the link I send was the direct link to the 21w10a version.. but it seems like the world edit devs removed that build.. when I posted the link it was still working. Now I can't find the version on their build site anymore.

I techically still have the jar file, but I don't think, that I am allowed to post the file here. So unless an admin (ie. an DimDoors or WorldEdit dev) tells me its fine, I won't post it.

Closed since this was caused by an accidental World Edit dependency that has since been fixed.
