Well, on my game, it doesn't matter if snowboarding half pipe is acquired via Buy Mode or redeeming tickets, both cause game to crash to desktop when attempting to save while pipe is on the lot...maybe there are other specific factors to the problem .. playing with latest patch to date, in Appaloosa Plains, at 1936 Beach Boulevard ... I like the time mod more than I like the half-pipe, so I will not experiment with removing mod or reinstalling... will just have to work around it ...
BTW, it only crashes when it's placed on the lot, I can store it in family inventory, save, and bring it out when needed... only a minor inconvience
