Just updated to the latest version of DBM. Looked fine at first, but hearthing to the Garrison (fast travel) it popped up with the following lua error:

what exactly did you use to update your addons?

The new Curse on Wolf

I can't find any reason this error would occur if you havae DBM 9.0.4 as well as updated all old sub packages too.

Updating DBM-WoD mods would have automatically removed DBM-GarrisonInvasions, but even if it hadn't, if you had DBM 9.0.4 DBM-GarrisonInvasions should have been ignored and not attempted to load it in first place, so soemthing odd is going on.

I'm gonna put it down to an Overwolf glitch. I force reinstalled it for now. and will see if it happens again
