Hello.  Just bringing to attention that the Pathfinder bug is still present, but I noticed a couple of other oddities.

1.

This first test was on a Normal game with some ridges present.  I had the commander roam about the map to test the skill and thought to split him from forces after a battle.  I put the injured Seekers in garrison and embarked Xoyos when we began floating.  I reproduced this at least once in two other games, however, it did not seem as though it mattered whether or not an army was with him.

2.

The rest of these were done on Fast.  This first image shows the starting army having gone into the Fog of War.  I had them on the tile next to the anomaly and right-clicked repeatedly in the direction of the Fog when it occurred.   Not sure what happened here exactly but he simply turned from the last forest tile on the left up into the mountain tile.  I tried exiting a few windows and clicking about to see if the issue would correct, but they simply stayed that way until next turn.

3.

I began to return the army to the city when the displacement bug occurred.  It shows the army on the tile underneath the ruins.  At this point, I chose to detach the leader.

4.

On the following turn, I detached the leader to the forest tile on the left which successfully worked and returned the models to their correct locations.

In addition, I wanted to ask if Pathfinder is supposed to be applying to cliffs.  I distinctly recall Xoyos flying over cliffs when Shifters was released and I was trying the Allayi out.  I tested out these maps with Many and Everyhere Cliffs and Ridges settings to see if he would perform the movement, but the unit simply takes the most routine way around as other units do.  I feel like the issue is with the Allayi Hero's movement behavior conflicting with terrain or some sort of momentary "applies flying movement" signal.  I tested out the other units including Skyfin and Settlers and have not found them to have any sort of issues.  I have yet to perform any sort of movement tests with those units under the Allayi heroes.

Apologies about the small thumbnails.  Open images in new tab for the correct image size.

After some thought, it would seem to me that Pathfinder skill is conflicting with terrain "orders" such as Embark or the "fly over cliff" movement which would explain why these bugs are present.  The ability to confer these movement rules/logic to the armies also seems to be an issue which could account for the displacement.

EDIT: Disregard cliff question.  I must be thinking about Monks flying over walls.
