If the LUA compiler has an error that results in it not being able to compile, the simulator will still start and complain about the version (nil) being too old
I would really appreciate that when this error is detected, the simulator self-terminate
Are you using the 1.11 SDK? If you fix your error, rebuild and press the retry button it will reload the game correctly. But you'd rather have it just quit in this case? Would a quit button be OK?
