Quickload makes the game unstable

[Cosmus]

I like to quicksave before making significant maneuvers. However, every time I quickload something bad happens to my spacecraft. Some parts just fly away even though the game still considers them to be attached; When I stage a decoupler, the camera won't focus on the cockpit anymore, which flies away from the camera and now I am stuck focusing on the void. Is this normal (as in, is this a known issue)?
