-I have no idea what the purple-coloured car/bike means, they are not abandoned, but in use/moving around? After a while they dissappeared.
Purple car/bikes are those which are derelict. If they are on the road and not moving, this is a bad sign. If they appear only briefly, that's probably because the tracker spotted them right when they spawned, before the sim popped into it. They may subsequently change color or start moving, which means they are fine again. Those that AREN'T moving, if they are on the road, were abandoned because a sim was ejected from them while driving, and now they are stuck on the road. Placing the owners on Supreme Commander will cause them to reclaim their vehicle. I may also include a "Dude! Where's My Car" action that will let you order it immediately later.In my game, using AMS 8/30/2009 09:50 AM, placing the owners on Supreme Commander doesn't result in the owners reclaiming derelict bikes, and 'towderelicts' doesn't seem to work for bikes.
My game froze going from Buy/Build Mode to Live Mode (on any lot) and having to kill the game with Process Explorer (task manager). In this thread that problem is described without mentioning AwesomeMod. Deleting the cache files (in \My Documents\Electronic Arts\The Sims 3) and using 'Save As' as suggested there only work (for me) when not using AMS. The moment AMS is used again the freeze is back.
The reason I'm posting in this thread is that derelict bikes apparently can cause this Buy/Build Mode freeze when using AwesomeMod. Getting rid off the derelict bikes using NRaas Computer (Master Controller - Maintanance - Objects Stats - All - find/select/purge the bikes) could solve the problem for AMS users, it did for me.
