on Klenczonem turn 46, I have 6 heavy infantry near Tayuna (center-west of the map), I moved them in the town, but now they appear to be where they were before, and I cannot select them and move them again. I tried already everything (deleting cookies, log-off and log-in again, reloading the page, clearing the cache, nothing worked).
Solved. I sent a Pegasus to that square, I could select all units except one that was somehow stuck, and I could move them. Then I reloaded and I could select and move also the last army. A bit strange, but in the end it worked.
