Thanks much Myth for the info, I finally got around to fixing the online bug. By process of elimination discovered the problem is the particle system I used. It causes the match to freeze after about 20-30 seconds. I removed the ps actors and the map works fine when I run it on goty 436 in HOST mode with 12 players/bots, but there's no snow falling in the map (oh well). The particle system is "ParticleSystem42" which originated in map DM-Deck40 by Bot40....However there seems to be a bug that makes it impossible to it play online on a 440 server.
Now I suppose I should release an "SE" version for servers. Before I do that I would like to know (maybe a server admin knows) is there a particle system around that actually works on servers? or is there something special you do to get ParticleSystem42.u to work online?
Any advice is appreciated
And thans again Myth
