Another thing I have bee encountering is rains that finish loading/unloading, and their next command is a navigate/drive command and they just sit there looking dumb. When I find the culprit, I jiggle the command like I'm gong to remove it, let it drop back in, and the train continues. It's happening often at the diesel unload bay of the coal mine, and less often at some of the MIN setups I have. Tried changing drivers too. No luck. It's random when/if it will happen too. More weirdness.
