Dynamic Rocks (for race) are static.

Not exactly a bug as I'm guessing you know it already, but I'll say it anyway.

We were playing yo-yo maps in MTA and all the players discovered the rocks in race are no longer dynamic. There are many maps using dynamic rock walls which have now been made rather difficult to complete (we had to motorbike accross a hairs width ledge to get round rocks (I never made it accross )).
