Assembly

I havent play for a week or so in daily races so 3 car\'\'s parts wore off. i pressed to switch them with new ones, but they did not switch before race and even not after. when they should switch, and please, do something because i just not participating in races and losing points. thx

I think when you were replacing parts,you may forget to save those.

Or,the preparations may be locked.So that ,though you refit some parts,due to locking,you may not be able to change it.
