Mass object shift?

[Naphtha]

Working on the fourth level of my mission, and something very bizarre happened between the last time I saved the map and shutdown the program, and when I started it up again just a few minutes ago. Every single object on the screen appears to have been shifted about forty units or so out of place. I'm figuring this is probably because the coordinates of the mine try to equalize themselves at the center every time the size changes significantly, but I'm not sure why the objects got left behind. But is there a way to move the map as a whole without the objects, or select all the objects and move them together? Or am I going to have to move them all back into position one at a time?

I take that you haven't saved any changes since you discovered the error?

When was the last time you updated DLE-XP?
There has been some new updates in the last couple days.

Try updating and reloading the level to see if it does it again.

Sadly, I did end up saving the thing as I was working on the last room before I noticed what happened. I'm not that far behind on the updates; currently using 1.8.92, but I just updated and the problem is still there. Not only that, but I got this warning:

"Robots number (0) out of range. Range= [0..-1]."

I don't think I really understand what that means, if that's something other than the displacement issue. It didn't show up last night, so it might be something different, for all I know. For now, I'm just going to see if I can relocate them one at a time by hand, but I'm definitely a little surprised there isn't an option to mass-select and move multiple objects together.

Mine co-ordinates actually don't change (or, at least, I've never seen them do that before). The objects moving is ... well, who knows. Stranger things have happened
