Bug description

I just log in and then my chat is spawned with this error.

Screenshots

Questie version

v6.3.14

It has to do with being on a new dungeon quest while using Objective Sorting > By Proximity in Questie Options > Tracker.
For now: Change to another sorting or abandon that dungeon quest until you're doing that dungeon.
We'll try to have a fix out for next release.
Thanks for the reports.

Fixed in v6.3.15
