Had a quick look and I can only find one thread on this with an answer that does not make any sense so ..
My not enough items interface has stopped working, all I get is my bog standard inventory screen. The problem first occurred on a server, so I tried a single player game, same issue, so I changed the VOLTZ build to update the pack, same issue, so I re-downloaded the Technic Launcher, and I still have the same issue.
Anyone come across this, or even better know how to fix it?
Thanks in advance
