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

Which version of SavedInstances are you using?
9.0.4

Was it working in a previous version? If yes, which was the last good one?
It worked fine 2 versions ago.

It's a bug related to Mythic Plus Best weekly reset feature and won't try to fetch new status. Will fix this later today.

maybe 5e6e753?

I'll try this afternoon afterwork thanks 👍

After commit merged and update to new version, you might need to login all character affected to refresh corrupted reward waiting info to stop them showing. Sorry for the inconveniece.

I've just tested this changeset and it works fine, al least for me :)

As the new version go live, this issue can be closed.
