Ever since I discovered the carts I thought they were great, mobile and very very useful. I even made roads and bridges, and it worked wonderful. Until today. My cart got stuck on EVERYHTING, including slightly tilted ground, which never caused any problem at all. And when i tried to tip it forward by raising land it tips the wrong way and get sucked backwards instead. And it can't even get on the bridges anymore. Just stuck. I basically had to demolish parts of my roads and bridges in order to get the cart to move just an inch.

Any idea what could have caused this? I spent hours (and in-game days) just to move short distances.
