Hello good folk!
This map isn't an issue, but a certain area is, if you load at Universitat, fine, if you go to another entry point within the game and then spawn back, the scenery has disappeared and is showing this. I've posted the log file but the problem is; no one really helps beyond that, so what I have noticed are the following;
B_SWS-E.ttp has an invalid track (busstop nr. 1 or 2) a Betriebsfahrt trip to Eichenhoe depot.
Various entries which state tracks finish before the next one starts, all warnings. But then I get the repetitive Fehler Bei error, map.translate
Fehler bei Bereichsprüfung: P.TL: 10A
Busstop Nr. 1 on trip "maps\Ahlheim 5\TTData\B_SWS-E.ttp" has no valid track segment and is invalid!
Again it's just around the Universitat, if the authors know what tiles these are, I can take a look to see if there's any characters which cause an issue, but so far in my OMSI gaming life, never really had this issue before.
EDIT: Solved it, deleted the map, reinstalled just the 5.0.1 hotfix only and that works. So to anyone else, just install the map from the Hotfix, and ignore the download packet 1, just use 2 and 3 and the hotfix.
