In my new coaster I am making, there are about 4 brake runs in it, the train leaves the station, goes up the lift, gets to the first brake run, and just stops moving (the brake run does have friction wheels). it just stays there, and when another train finishes the lift block, it doesn't stop at ther top of the lift, it just keeps going and crashes into the train stuck at the brake run.
An even weirder part of this problem is, when it was in shuttle mode (while i was testing while making the coaster), it just went straight through the brake run, but as soon as I changed it to continuous, it stops at the brakes.
Also before you say there are too many trains, there are 3 trains and 5 blocks.
What's wrong?
