Nothing too much out of the ordinary here.
Differences with my conf.ini OpenGL:
TexMipFilter=2
TexFlags.UseDither=0
TexFlags.TexAnisotropicExt=0
You must realize this was a very special occasion:
1. Host was running 7.02, where most of the clients were running 7.01
2. From the very start of the mission, the moment Fen pressed 'Fly', my eventlog.lst file got filled up with java.lang.nullpointerexceptions, at com.maddox.il2.objects.trains.LocomotiveVerm.place(LocomotiveVerm.java:147), over 25 of these messages per second were generated.Resulting in a log file of over 500Mb's.
3. Crash's game also hung itself, albeit at the end of the mission. (And, I think it happened to some else too...)
4. I could not really use track recording, switching it on resulted in a massive pause - about 4 to 5 seconds.
5. ...
I would not be too worried about this one occurence....
I have checked the mission file running 7.01 and 7.02, the error that occured on Tuedsday did not occur during my test.
Sure, it was a limited test, me hosting, with no clients. But it shows that there are no basic compatibility issues with the mission file.
Me thinks the large map, long mission + the 7.01/2 combo did it, and maybe even one of the clients was still 'in between' them versions... (Starting the autoupdater, it ending prematurely due to a connection issue or whatever error...)
