BeamMP is unpacked and can't be packed

[Protogen_1]

Issue

BeamNG.Drive reports that there is an unpacked version of BeamMP.

Solution

1. Open the BeamNG.Drive mod folder. (you can do this from the BeamNG.Drive launcher popup upon startup)
2. Delete the unpacked folder, as well as the db.json file.
3. Relaunch the game.
