4x4 Adventure Cars not working properly

[lottebauer1986]

Has anyone else had problems with the Adventure car ride. Made a Zoo yesterday with a track in it, it worked fine for a while but then suddenly stopped letting ppl on even when they were in the que. Today tried to make another zoo with a track in it, and even tho the track is open and running no guests, are going in the que at all, there is nothing blocking the path ot anything.
