I was recently flying on Training Server and I had just taken off and my A318 decided that it would be a wonderful idea to stop following my yoke movements and went vertical, resulting in my account getting striked with an aerobatics violation. I attempted to close the app before I received a violation, but I had Guided Access on so I didn’t accidentally swipe up, returning to my Home Screen. Didn’t think about ending my flight as I was trying to get my plane out of the vertical position.
A similar problem happened yesterday twice, on my takeoff roll, luckily I was not climbing and just ended up crashing a few feet after the tarmac. This time I wasn’t so lucky.
