Describe the Bug

I have a minecart with a furnace with a minecart coupling to another minecart and when the two get to a track going up a block (not every time), both of them stop or turn around and go the other way.

Reproduction Steps

1.Attatch furnace minecart with a coupling to another minecart
2. Send down a track with a block up track and turns
3. Watch the minecart stop

Expected Result

The carts continue down the track.
