I tried to replicate a bunch of different capsules, but, everytime I get a weird effect in which when the parachutes are opened in the atmosphere ( this bug were already active since 0.7.9x versions) the capsules start to spin faster and faster as the atmosphere get denser .
The only thing which avoid this problem, is to lock the craft on retrograde if it has reaction controls or gyroscopes.
Steps:
1-Play normaly, using , for exemple, the basic capsule present in the "new rocket" craft or in my slightly modified craft.
2- Launch the game and put the capsule in a sub-orbital trajectory, let it fall .
3- Before activating the parachute stage, unlock the heading and let the craft free of movements.
4-Activate the stage , wait until the parachute is completly opened , (stabilise the capsule, if needed, by locking heading on retrograde for 2 secs) and observe that the craft starts to spin faster and faster.
There is a video ( bad quality sorry ) of what I experience with: SADNESS
Have good day, please fix this, it's so annoying even more when there are multiple parachutes. :'/
