Summary0013058: Crashes when moving goods to trade depot. |!Uses likely irrelevant mods!
Description
I built a walled off trade depot and when i try to transport goods to it while it is locked off by bridges, the game crashes.
with to another raised bridge inside.
At the moment of crash, there are two "pull lever" tasks that would lower the aforementioned bridges.

When lowering the bridge, i can move goods to the depot as i should. When raising the bridge after lowering it, i can trade no goods, as i should, without crashing.

Initially, i reproduced this bug without issue for two times in a row. Afterwards trying to test for more info, i couldnt reproduce it anymore. Then, i reset the game without saving, and it worked again. Apparently one "non-crash instance" on this save prevents it from being reproduced until the game gets restarted; im not quite clear.

Steps To ReproduceSimply keep the game paused (I presume unpaused works just as well?) and move to the trade depot on the top of the map on the surface. Will add file link in comments.
Additional InformationLowering the bridges allows moving goods as normal. Subsequent reproductions of the bug on that same launch of the game dont reproduce it. Restart the game and the bug will be reproducable again. Off of this i would presume its some on launch mixup to do with hauling routes, where dwarves dont "know" the bridges are raised, and because of that calculate impossible routes or the like, with one successful manipulation of the bridge somehow setting it properly. However, one time i lowered and raised the outside bridge, so im half unsure. something like my theory may still be the case, as the "inner" bridge would likely be the shorter path. All my theories may be completely wrong, but please still note the way the crash becomes temporarily irreproducable.

Uses Interface Tweaks 1.6, More Civilizable Creatures 51.01, No Aquifers 1.0.1, Civilizations support more biomes 1.1, Tobb's War Crocodiles 1.1, Transparent Glass Floors 1.0, Valuable Underground Trees 1.00. These all dont seem like they would have any impact on this bug occuring in vanilla.

You can find this save at https://dffd.bay12games.com/file.php?id=17284
It doesnt seem too urgent as you dont seem to lose progress by it; i doubt this can occur on longer running saves (unless some really unlucky circumstances coincide), and on fresh launches it is easily avoidable once aware of it. Nevertheless, its a directly reproducable crash.
excuse the delay, rate limited (presume because adding notes "took up" my hourly action limit)
