Hi, sorry for very very late answer...
I think you were right and there was a problem of locking (a list of DistantComputer) in network game. It is normally fixed in the branch 0.8.4 that is not yet released. It would be really great if you can test it!! You can get the code using this instructions : http://www.wormux.org/wiki/howto/en/subversion.php replacing http://svn.gna.org/svn/wormux/trunk by http://svn.gna.org/svn/wormux/branches/wormux-0.8.4 Regards, Matt (gentildemon) Matthieu Fertré a écrit : > Hi, > > Stefan Sperling a écrit : > >> Hi, >> >> wormux is a great game :) >> >> > > thanks :) > > >> I got the following crash from wormux-0.8.2 while playing a networking >> game on OpenBSD.
