Summary	0008419: Wagons cave in and get destroyed when unloading goods when trade depot is build over floors build over volcano
Description	I've embarked in a location that has an active volcano and have proceeded to build a floor over the top of the volcano over the lava to seal it up. Then I've built a trade depot over the floor. In spring an elven caravan arrived (no wagons) and all went as expected, no issues. In summer the human caravan came with wagons. As soon as a wagon started unloading, a cloud appeared similar to a cave-in or a fireball and all wagons entering it, including merchants, were destroyed for no apparent reason. The other merchants remain lost on the map and i can no longer trade at the depot for the duration. I've loaded a previous save game from the start of the summer to see if this is reproducible and it appears to be so.
Steps To Reproduce	https://www.dropbox.com/s/p9usa2bj5aarsw0/region1-00245-04-01%20-%20Copy.rar?dl=0 Dropbox link to download the summer save game, right before the trade caravan arrives and the bug occurs.
Additional Information	I had a trade depot in a different position, but i destroyed it as soon as the new one was built. There is a floor grate next to the trade depot with access to the lava for dumping purposes, but there are no lava imps or other creatures in the volcano at the time of the trader's arrival and no report to indicate any combat.
