Are you using the awesomemod config tool to generate an aweconfig.package which will load your age scaling settings or are you setting those each time you load your game?

I can definitely confirm this as well. Seems to happen with children riding personally owned bikes as well as adults. Sound goes wonky, game slows down to a crawl. if you save the game in this state, it stays in that bugged state. EA strikes again! I looked all over the web before I found this forum which actually addressed this issue. Not even EA's tech support forums have anything reporting this one. Note: If a kid rides the default npc-pool bike, this issue does not happen. Dunno so much about adults. I usually get them Kenspas for traveling around China for example. Issue doesn't seem to happen with Kenspas.
