During the finale in the map “Into the nest”, when played with bots, Bardin got stuck twice in a row in the stairs. During one run, he blocked Kruber as well. During the second run, he was the only one stuck.
The games were played in Veteran difficulty, and of course the bot later got teleported, but it can have an impact if there are some enemies left between the stairs and the moving platform.
Here are two screenshots of the issue :
