I spoke with Paul and Aren at VEX this morning and they let me in on what caused the problem with 4" Mecanum wheels.
VEX shipped the 4" Mecanum hubs with the rollers for the 6" Mecanum wheels as a stop gap since the 4" rollers weren't ready. The 4" rollers are apparently in Greenville now and will be shipping out to all the teams that had previously ordered 4" Mecanum wheels.
The only real issue with all this is they didn't tell anyone they were doing this. So we wasted a whole lot of week 4 playing around with wheels that aren't round. Now we have decide if we want to switch back to actually round mecanum wheels or stay with the omni wheels that we put on our chassis yesterday.
