Ok, I've started workin' on the updates from LU 16, should be ready by sometime tommorow, I hope.
Damalion, did you check under other windows, and see if it wandered off on you? Mine also changed position for some reason after LU 16 patched, and was underneath one of my chat windows.
Let me know if you're still havin' troubles finding it, though.
edit: forgot to add - I'm also going to incorporate a change to the group window, take it from health percentage at the end (which isn't working) to current / total health. Hopefully, that'll help out a bit, until the Dynamic Data starts working. *sigh*
