I was trying something Yesterday in the game (because I'm not really playing anymore atm) and hell... I wanted to climb a ladder....
Ok the first climb the ladder. I didn't move him too much because it was on a small platform so no one followed. So I had to click the others companions and I forget to "disband"... The first one go down, then everyone finally climb that ladder...
This is really cheap party mouvement management. If this game is really ambitious, they have to change this even worse mechanics than 20yo mechanics.
