Have issue with multiple version of same track in new UI, I have tried unsubscribing and resub but issue still there, for example I have Brookdale version 1.04 and 1.15, Northside version 0.435 and 1.10, all older versions do not show a track layout. These are just a couple examples. But these are ISI tracks the others are third party.
This is still happening tried reloading tracks some of the tracks were because i had Machines oval tracks loaded but Portland have 3 versions 0.18 , 0.40 and 1.04 Nurburgring 0.455 and 2.19? and the older version there is no track layout in new UI and can not even select the ones with no layout.
The Problem is, that if a Workshop or DLC Component gets an Update, the old Files don't get deleted, because they e.g. are in use by another Update or a vmod. In such Cases you can delete them manually. But be careful, because many Components do have 2 Folders, like the Nurburgring for Example, where the current Version has the Folders 2.18 and 2.19.
