I've come across that question.
It asks about a bug in the game-engine and was therefore put on hold, since it
should be reported to the official bug tracker.
Considering that the game engine won't be in 2.8 anymore, I guess nobody at BlenderFoundation cares anymore about solving these bugs.
Shall bug-concerning game-engine questions still be flagged and put on hold? In my oppinion this will make it even more unlikely for those who ask, to find an answer.
