I'm using the very latest development release of nui+. I think I've come across a bug. My attacks on the 1-= action bar are not displaying the enabled/disable status or the cooldowns correctly . I've gone back to the previous version of nui+ devel and that working fine. So it's only happening in the very latest version.
That's pretty much new code in the action bars trying to fix the taint problem that was just unercovered this week, so this is probably a new bug I introduced in the new code. I'll see if I can track it down and get another update out tomorrow.
What people don't get is that I am, ultimately, an artist at heart. My brush has two colors, 1 and 0, and my canvas is made of silicon.
