Pasting a lua error below.
When you exit a BG like Arathi Basin, the game drops to single digit FPS
and carbonite experiences a constant slew of LUA errors

reloading UI clears it until you enter and exit another battleground.

Carbonite has all its modules enabled

@IrcDirk
Hi, i dont want to reopen this, as grabbing source from here cured it.
But do you know why curse/twitch does not use your proper updated stuff?

Heh, it wants to go "update" carbonite with one that is outdated and would just give the problem back, which is probably how i wound up suddenly having the issue to begin with
