Kerbal Space Program

There is an issue with the forced symmetry mode when attaching parts to objects that were placed with a certain symmetry mode. I have for instance experienced this issue with adding nose cones to a triple booster setup and am now seeing the issue again on a rocket that has four external fuel tanks. When I try to attach parts to the fuel tanks with the correct symmetry (4 radial) pre-set it works fine but when the symmetry mode is set to another value the VAB is forcing the symmetry to four but before is can show me the game hangs for a moment and then disappears.

Unfortunately the logs do not seem to show any errors, I include one here anyway. At the end of the log you can see me successfully adding some nose cones with the correct symmetry pre-set and then removing them again. What you don't see is me trying to add them again but letting the VAB force the symmetry and subsequently crash.

This whole thing would not be so bad if this was all. Just pre-setting the symmetry mode before attaching parts is an annoyance but not too bad. The main issue is actually when you want to attach somewhere else and accidentally touch the wrong part.. boom game gone and all of you tediously build craft.
