While trying to figure out how to add more builders to an already started facility construction I accidentally aborted the construction of that facility. (ID# 273208) I know this is a very long shot, but is there any way to undo the abortion?
Just in case you haven't found out yet, you can't add more NPC's to something already under construction unless you arrest the existing NPC's so it stops being built first. Though i've never tried that so I'm not entirely sure I'm remembering rightly.
They are still working on it, but it was supposed to take 9 days, which was my original problem, I didn't know it wouldn't be instant. Also no materials have been loaded into the ship, but maybe this happens at the end. Since I can't do anything about it now, I'll keep you informed on how it goes.
The effect of the abortion: The NPC's stopped working normally, roads are still there, but according to the rules that seems to be normal Kyle. The one thing that didn't go right though is that I got no materials back at all even though the ship has more than enough storage room.
