Are you sure you're on v0.2.5.0?
Or is it 0.1.2.049?
The lock and "doesn't move" sounds like 049/054
You can try, I think some people saw reaction from grabbing it and using rotation (Alt/ ctrl and alt IIRC) to cause it to move again, for job crates.
You'll also need to just avoid putting them into the cart because crates, the wagon, and the job crates, are all "basically the same" and the lock on the wagon is similar to the lock on the crate which is similar to the job crate albeit quite different to the two in some ways - But, the locking of each of those can affect the state and locking of the others, with the wagon completely encompassing the other two due to size.
