Builder works in singleplayer, but it doesn't works on the server

is there anything permission related on the server that might be blocking it from building? things like sponge or other permission plugins?

also make sure you are not building in the area arround spawn that is protected

Yes, i have server on the Thermos with PermissionEx

I deleted PermissionEx, but the problem did not disappear

try /buildcraft op

How to do it?

Just write?

just type that in the chat ingame

Don't works

are you op on the server?

Yes

any other mods/plugins that might be related to permissions, please try to reproduce this with just BC

if it still heapens it is most likely an issue with thermos

@0othomio0 Permissions were always a problem. Thermos will probably break BuildCraft in other ways as well - we don't recommend using it.

gona assume this is a permissions setup issue as it works on a regular forge server and others have gotten it to work just fine with permission plugins
