Please explain the issue is in as much detail as possible: A party member has a leopard as a companion. Almost every time I open doors to enter a room, the leopard gets stuck behind the door and can’t move. Only when I go down another level does the leopard join the party. The animal can’t move in any direction, and is basically useless, despite being medium sized (I’m not level 7 yet). Another animal companion, a wolf, does NOT get stuck in the door. Just the smaller ones.
