Bug: Possibly artillery bug?

[Kovski]

Here's another problem I discovered in my last PBEM game:

I was relocating my mortar units, and when I disembarked them from their trucks, one of them came under sniper fire and was pinned. Now, when I was plotting my arty strikes that turn, I noticed that the pinned mortar could be plotted, while the ones that were in ready-status could not, having moved that turn. In effect, getting suppressed seems to remove the moving-status from the arty unit.
