Is this covered by 0005903?

It could be related but i don't think its the same. Unless deleting stop 1 is being treated the same as promoting stop 2. I believe my crash occurs when someone tries to do something with the cart...not instantly. I got the impression the other crash was instantaneous?

I think you're correct.

Sounds kinda similar but nonetheless unrelated to me, as the original reporter of 0005903. Mine was indeed instantaneous. In this case it sounds as though the minecart still has a pointer to a stop object that has been deallocated, or something of that nature. Whereas I think my crash occurs because the actual position of the stop is taken for how many times it may be promoted when the display position in the menu at the time happens to be higher up and thus possible to promote out of the display menu, which probably crashes it because it gets moved past the first entry in the display menu's list/array/whatever.

I could be wrong about either of those, though.

I've also see thism removing a stop cause a crash when the next event on the route triggers. Also I just had a kea steal one of my lumber minecarts causing a crash straight after.

I have gotten similar behavior (crashing) after deconstructing a track stop that was still listed in a route. I'm thinking Cobbler's hypothesis of the route holding a pointer to a now deallocated stop could very well be what is going on.

I'm getting a crash that I thought was because I was assigning a cart to a route without a stop, but after testing with a fresh embark, it looks like it's this one, or at least that crash is closely related.

With the main save, I removed a route and stop a while ago, so I don't even remember which cart was on that route. I tried rearranging the carts around to different stops, didn't work, but when I made a stop on the route, it was fine, even rearranging carts was fine.

I was going to make a new bug report, but it seems closely related to this one because on the quick embark, I did put a cart on a route without a stop and it didn't crash, tried switching the two carts I had made, didn't crash either.
