Thanks for taking the time to register and post a bug report! Yeah, there was a bug awhile back w/ dragging items in the inventory causing crashes, I suggest updating to the latest stable version (4.18) as we have it fixed there, though you might have to start a new campaign as it might not be compatible with your current version (4.12.2)
Thanks for the bug report! Unfortunately, the save attached to the bug report zip file was after the convoy ambush mission it seems (due to it being an ironman campaign). So I'm assuming you were able to load the save again and finish the mission?
That's strange, it works normally on my end. Did this only start happening on 4.21?
EDIT: Have you tried changing to the different window settings? (borderless, etc)
Thanks for the report! Not necessarily a bug, but I see what you mean. Soldier rescue maps and abduction maps set on the tropical biome will have a chance of picking dockyard maps due to the tropical and dockyard assets originally belonging to the same biome. We plan on fully separating these maps once we've got mroe assets for the tropical biome
I might be wrong but iirc it's because the tooltip spawn delay settings didn't reset properly when moving from one button to another, so it'd end up showing up even though you've just hovered the cursor over it
Thanks for providing the saves! I tried loading the most recent (Day 51: Manual Save) and I didn't experience any crashes while testing it on 4.18. Can you try switching to the experimental branch and see if it still crashes?
Unless I'm misunderstanding things, I think the alienbase walls were destroyed by the explosion? In this case, the missing walls aren't really missing, just destroyed, thus revealing the dirt block behind it
Thanks for the bug report! We'll get it fixed. Although to clarify, I think you meant Abductor UFO? If a harvester (large UFO) spawned in that map (medium map), then that's going to be a separate bug that needs to be looked into as well.
