One of the planes i have been working on has no collisions with any other crafts whatsoever. I have made sure to check if my part collisions are on and they are. I'm wondering if anyone knows a fix to this. Thank you.

Ok so I have found the issue. The control stick for the joystick inside of the cockpit was attached to one of the fuselages in the plane disabling all of its collisions. I have a theory why it does this. I believe that when the joystick was attached to the fuselage it tricked the game into the think the whole plane was a joystick. The plane loses its collision because when anything is placed on top of a joystick base it loses collisions with anything but the water, ground, ships, and ground targets. If anyone needs help ask in this thread but i may take a while to respond as I am not very active on this game anymore.
