TInv not working/updating

I must say, I do seem to have a special ability to attract bugs…

My TInv has been at 1.8k DP and level 21 for quite some time now, and despite the fact that I have a purple color on the TInv it is not updating in-game (not that I dont prefer my green). It also seems /buildmode is a bit derpy, saying its an invalid command

Any known fixes?

There is no buildmode anymore.

What a shame, I must say.
It was me favorite command ;-;
