Bought rank upgrade, lost access to /sneak.

Hey there,
Today I got a rank upgrade to mayhem+ (from mayhem), but strangely it no longer gives me /sneak. It comes up with an error message.
Plus, some of the armour colours are glitched (Halloween and christmas don't change colour).


Thanks for reading

P.S. Apparently I am still sneaking. but I don't know when I am or aren't and cannot toggle it..


Edit: The Snow Blower gadget also doesn't work, says I need Mayhem+...
