To TrainFever devs:
These things may (and probably will) happen in the future too as you release new updates to your game. I would strongly recommend you to get a digital certificate and start certifying your binaries. Heck, even your main executable doesnt have the file version info (?!) AV compaines like certificates because they are easy to whitelist so you would solve the false detection issue once for all.

PS: Great game 🙂
