Has anyone else had a friend join their game as a gnome, dwarf, or halfling and constantly leave them behind because of the game’s pathing combined with the shorter jump distance?

I have a friend who joined as a Gnome Rouge and when I play solo with his character it seems like everytime the path requires a jump the ai pathing decides that he can’t make the jump (typically he can it just requires human input).

It’s one of those things where if you catch it early it’s not an issue. But getting into combat to realize 1/4 of your party is half a map away is annoying.
