I'm not sure this is the right place for this topic, but i havent found the issue using the search engine.
Each time you want to fly a Springblossom that is docked in a Kyoto when you are IS, switching to the Springblossom (Y then L then clicking the springblossom in list then X) always make you crash on Kyoto during the ship exit sequence. It seems the hitbox for the Springblossom is either too big or the one from hangar too small

Zooming out a bit while exiting, that might be because of the hangar doors closing on the tail of the Springblossom.
Even if you accelerate asap exiting to max speed doesnt help.
Only way to use a docked Springblossom when you are inside the Kyoto is to issue it the order to move to your position, click it in space and board it (X).
