Getting kerbals who are in EVA to switch between two ladders got harder in 1.1 / 1.1.1 / 1.1.2. Here's the bug report, so I'm not posting more details here (but can if needed).
I'm wondering if anyone has tips they've discovered for mitigating this, e.g. how to line up two perpendicular ladders in a manner that makes the transition more reliable, use of 45 degree connectors, etc.
