Me and a friend have been playing a world, everything was going fine until we couldn't fly anymore. we made a runway for our plane, and it was all going well, but we took off and the nose just went straight up. We didn't change anything before it started to do this and it was the same ship. Pressing W makes our nose go up, and S makes it go down. It makes it impossible to fly steadily, and holding down W makes you just do loops, and makes the nose go up unaturally fast. This mod also made it so when rovers are handbraked and you press W your nose goes down... any help/suggestions would be great.
