After landing at Duna I stepped out to EVA and planted a flag. When I returned to the vessel the UI that tells you to press F and B appeared but I couldn't grab the ladder or board, I took the second kerbal to EVA but didn't let go of the capsule ladder, but still couldn't board.
Quickloading doesn't help. After restarting KSP 2 I can grab the ladder and board, that is until I plant the flag again and the problem returns. On the 3rd restart i can't recreate the problem.
