New Weird Bug I Found

In a 1v1 I had troops in Paris: France and sent 6 infantry from Lyon: France, but they couldn't reach so I took the 11 Infantry from Paris to join them and put them all together in Paris. When the turn stared Lyon was turn blocked and my Infantry from Paris moved out of Paris (In the wrong direction) and stayed there making my opponent letting my opponent capture it. I have no idea how this happened because usually when the 1 city I send units from is turn blocked it doesn't make the other units from the other city get out of the city its in.

This isn't new.it happened to me a long long time ago when I was facing undisputed and I capped him because something like this happened.

Also strange the player sent 1 infantry and 4 bombers to combat my 11 Infantry. It seems as if he knew what he was doing.
