WORST FORGE BUG

I was forging a splatter monkey map, if any of you know what that is. Basically, you have vehicles and they boost up to a platform to splatter people that are shooting at them. Anyway, my friends joined and got in the vehicles to test. I was selecting the group of vehicles and it got them all out, and I tried to move them, but something weird was happening. I saved and ended the game, kicked everyone, and went back in. All the vehicles were unselectable, as was everything else I was using at the time. If I look at it in forge, it thinks I am looking into space. However, in Spartan mode, I can drive around in the vehicles, and the teleporters appear to work fine. I can’t delete of move the objects. I tried to move the messed up vehicles with a block, and forged pretty much crashed. I have no idea what is going on, but this needs to get fixed. 343, HELP!
