To Reproduce
Go to an instance, like Temple of White Tiger
Interrupt something

Did you try having DeadlyBossMods as the only enabled addon and everything else (especially something like ElvUI) disabled?
No

Which version of DeadlyBossMods are you using?
8.3.20-1-g46bdcef

Was it working in a previous version? If yes, which was the last good one?
Sorry, can't remember exact version.
