I'm afraid I've run into the same problem after recent update.
No error but no tankpoints info visible on items tooltip either.
I have checked to show difference in options.
Tankpoints r38293 and StatLogicLib r38404, enGB client.
I updated a couple of other addons at the same time but only ones whos changes
were even remotely related to tooltip code are dkpmon and xloot.
Guess first step is to disable those to see if it's some kind of conflict.
