My solution won't help if there's an internet connection issue :D. For example, if the game is played through a router. And so on.

We don't have any internet problems; I don't think it's anything special that would cause it to lag or disconnect...
We just played a one-on-one game, and it kept freezing or disconnecting, but we somehow managed to finish it... What a nightmare!

I don't know what to do anymore... This game is causing so many problems; I can put up with it, but the other guys might not make it to this forum or participate in the games if this continues. ))

By the way, I want to note that 1-2 years ago, we played with three people without any lag or crashes.
True, we didn't upgrade or patch the game! And we installed it from discs; it looks like that's the only option left to try...
