What steps will reproduce the problem?

(i havent tried other vechile situations yet) In Iron Docks, my frames get stuck showing partymembers as their "Iron Star" vehicle after they exit the vehicle.
Forcing me to reload my interface to get back the correct units displayed on my frames.  

Did you try having Grid2 as the only enabled addon and everything else disabled?
no

Was it working in a previous version? If yes, which was the last good one?
I dont remember what version I had back then. But I always use the newest release-candidate available. And the problem showed itself the first time I entered Iron Docks after pre-patch hit.

Do you have an error log of what happened? If you don't see any errors, make sure that error reporting is enabled (`/console scriptErrors 1`) or install [BugSack](https://mods.curse.com/addons/wow/BugSack).
no errors occur

Please provide any additional information below.

This issue should be fixed in Grid2 2.0.64-beta, update to the latest beta version, latest grid2 beta version is: 2.0.66-beta:

I guess I should've checked that before I made a ticket.
I'll set my update on Grid2 on beta-releases for the time being then.

Thanks for pointing that out
