Everything is currently just "frozen" after a boss fight in Cinderbrew Meadery in a follower dungeon. This happened during a delve earlier this week too where it was showing phantom debuffs and other frame mistakes.

For comparison, this is what my party frames are showing (using ZPerl for now until I can replace it with Cell completely):

We're out of combat, only class buffs, and the only debuff should be showing is Time Warp.

Currently using r242-Release on Retail.

Refreshing unit buttons by right-clicking the red button appeared to fix it.

For some context, this appears to have only started for me this week with r242

Same here. Seems to also be the case for custom indicators. I have earth shield and water shield indicators and they either get stuck completely sometimes, or they show a wrong number (i.e. i have a talent to have 12 stacks of earth shield, and sometimes it still shows as if i would apply 12 stacks although in reality i only apply 9 after a talent swap).
