The JAA simulation feature is fixed now. But the new JAA version will replace the old one soon, and we'll be implementing a different "wheel rating" system, so which wheels are good or bad is easier to know.
From testing of the new JAA today, it is now very close to completion, but there is an issue with American 00 wheels, but it is very minor. We should be able to release it at the end of this week, if not early next week as I'd like to do more testing to be sure everything is ok.
