Steam Cannot Walk Through Cab (past Drivers Chair)

Slight problem here, I'm not able to walk through the cab due to the drivers chair, specifically I have seen this in the 375 and 323. I think this is due to a collision issue and means that you cannot exit the cab from the Drivers side door and you cannot enter the drivers door and walk through to the opposite (Secondmans) side of the cab

 

Check for outdated mods. If issue persists, validate your files via Steam.

No issues here.

 

I have seen this issue on the East Coastway Electrostar yesterday - haven't tried to recreate it though. I might try it again soon.

 

It just fixed itself - weird! It seems to be an intermittent issue...
