Describe the bug
errors randomly.

Do you have an error log of what happened?

To Reproduce
I think its when doing instances.

Screenshots

Did you try having DeadlyBossMods as the only enabled addon and everything else (especially something like ElvUI) disabled?
yes

Which version of DeadlyBossMods are you using?

Was it working in a previous version? If yes, which was the last good one?
yes, but idk which version it worked in.

Additional context

delete the offending weak aura that it's calling out (bosmutus)

which one might that be?

there is no "bostmus" wa

says "bosmutus - zu" then name is cut off. it's a bad weak aura in your wa's somewhere

weird

OK, FOUND IT..

Gonna guess it was https://wago.io/AnrlsJf97 or something like it.
an obsolete version of timeline yes.
only version of timeline that's supported and working is
https://wago.io/RaidAbilityTimeline
if you still want to use that anyways
