I'm suddenly seeing an issue with unmodded BAT 4.1 as well as with my personal mod based on BAT. The attached screenshots illustrate what I'm seeing. In the first screenshot you'll notice that the Explorer unit bottom center is correctly rendered but the Explorer in the upper left corner shows the original default graphics. In the second screenshot I've moved the first Explorer onto the Sheep. You'll see that now the other Explorer is selected and is now correctly rendered while the previous unit has now reverted to the default graphics. I figure this must have something to do with graphics being paged out and then back in, but I know next to nothing about how that works or what the possible corrective action might be. Thanks in advance for any help anyone can offer!
