Possibly - lately I've been having really odd errors pop up randomly - and switching the CSP version down, then back up to the latest version has usually cleared it. Sigh, remember way back a year ago when everything worked, and just kept working until the newer version replaced it... ? Last nights problem was wheels disappearing on GPL's F1 cars - when they'd been fine an hour before. Then the elevation went wonky on Legion's Monaco 72 track... flipping the CSP version returned happiness all 'round.
Anyway, it's worth a try, it's a simple fix if it works.
