Army units are not accepting control.

v100.12.6159.0
Steam
Windows10

During the multiplayer game, I used “Find All Military” (F2 hotkey) and “Attack Move” (SPACE hotkey).
Then all the military units stopped and did not accept controls.

I used the “Find All Military” key again.
They start walking in an unintended direction.
They approach the cliff, group up, and stop.
I try the controls individually. But it rarely works.
For roughly ten instructions, they obey only once.

My troops at that time are musketeers, scaremishers, militia, Swiss pikeman, and downed explorers.

The replay file was lost.
(Why are all replay files saved overwritten?)

Before the replay file was lost, I shot a video to show my friends.
