It seems to be just the SAFE behavior that is causing the issue. The speed does not matter. And as you wrote, it only causes issues for groups, nor individual soldiers.

Remember to vote for your own ticket! :)

Confirmed in dev branch

Confirmed. Move waypoint for a group with the SAFE or CARELESS mode no other things needed in the waypoint. The group leader gets stuck so other AI in the group won't move either.

If you put it on a lone soldier then you need to put limited speed to get it stucked because the stuck only happens when the AI is walking.

/Edited some better observations.

I made a video:

Confirmed ONLY with Safe and Limited, and with a single soldier, not a group.

Not seeing this at all in my Dev Build.

Kylania, if you used that mission from your forum post, try a longer waypoint without Cycle.

I'd tried a different unit with a single MOVE about 200m away but i'll try a longer one when i get home :)

@kylania Check my pervious post that I edited

200m should do it. Looks like a non-universal bug.

I just witnessed this bug in a procedurally generated mission that probably used waypoints created by script.

confirmed in dev branch!
similar bug:
lower weapon, walk slowly --> your animation will stuck but you will continue moving

safe and careless mode.

"lower weapon, walk slowly --> your animation will stuck but you will continue moving" is probably the same bug!

There was a bug similar to this in Arma (1), which was due to the FSM

Possibly related to #13512

Seems to be fixed now. Can someone else also confirm?

I can confirm it, someone can close it please.

Strange, I did not notice a patch downloading, but the problem seems to be gone
