[working]Gundam VS Gundam Next Plus

[LunaMoo]

Sorry, I'm aware through this thread that something broke adhoc in master, so my build also got it when I updated it last time, but I had no time to even reproduce it myself so far. If my last build was affected, it has to be something between v1.9.3 and v1.9.3-619-ga0cdf566c, maybe it was v1.9.3-498-g9aefc0108 as that's the only network related change, through it could as well be one of the many other changes affecting threading or other stuff.

Preferably the problem should be bisected as I wrote in here, which probably would be easiest by someone with 2 devices(or 1 pc with virtual machine as another pc) and builds from buildbot or 1 pc and with build environment and self-builds of any branch that allows multiplayer on same pc.
