With 7.8.1 and TFTDRework 1.13 I noticed something I have not seen before. On an artifact site mission, one of the aquanauts was knocked out in the first phase of the mission. The unconscious body appeared on top of second phase downstairs access lifts with all the loot. So you couldn't abort the mission without losing all the equipment or moving all of it manually. I don't think there are any changes in the mod, so I suppose this also affects the vanilla. I was planning to abort the mission and this was rather annoying. I wonder if anything could be done about this. Unfortunately, no save because I was playing IM and wasn't smart enough to stop playing immediately.
