Describe the problem

I'm not sure if this is Mapster or Buggrabber - have logged a ticket with Mapster as well

What steps will reproduce the problem?

1. Open a map with Mapster loaded

Consider attaching a screenshot below to help describe your issue (Attach directly, do not link to other websites)

What version of the addon are you using? (Stating 'latest' is not useful)

!BugGrabber-v10.0.0
Mapster-1.10.0

Do you have an error log of what happened?

Any additional information? (example: WoW language if not English)

This place is for reporting issues with BugSack, not Mapster.
