Beta updated to b3, failback to name when id is incorrect now works for priority, bar colours and filters. Previous when using ID or Name and failing back to Name, it would show the icon with priority 10 and no bar colour change etc.
Failing back to name may resolve a number of ID's not working correctly, seems ID's have changed or can change depending on certain conditions.
Please test the beta [220.127.116.11] at the top of this forum, confirm if this issue is fixed.
I'm on 18.104.22.168 (well, the TOC says 22.214.171.124 but it's the 126.96.36.199 download from Curseforge) and seem to have the same problem OP reported. I only use bar colors for debuffs and I'm noticing that a priority 1 or 2 icon will be present but the bar color will be that of a 4 or 5 debuff (that is also on the unit).
Hello, using version 188.8.131.52, the issue still persists.
I have two bar colors: White if single tank missing Earth Shield, and blue if ally is affected by self Riptide. In the video shown below, the tank (first bar from the top) has Earth Shield expire 10 seconds into the clip, and is not affected by Riptide. Instead of turning white as expected, his bar turns blue.
