Closing as won't fix: NaN is a valid result from some calculations, such as sqrt(-1). It's up to your game to either make sure calculations never result in NaN, or to correctly handle NaN if it is produced as a result. Please also refer to the bug report guidelines, we do not generally accept .capx files like the one you provided in bug reports.
