With the newest release i cant use target UF. It's all grayed out in options.

Hi! Are you sure you're on the latest version?

I tried reproducing the bug, but everything seems to be working fine on my end...
Any error messages? If you don't see any, install buggrabber + bugsack and then tell me what you get.

I'm asking about errors because your player power bar is white which usually is a result of something being broken.
