When you say you played using a proxy server, what do you mean? Are you talking about something like Tor, or a local socks proxy or ? I believe it to be a networking issue too, I'm just curious if it's something that I can alter and test.
just a VPN program i got off google, not gonna say which since I don't want the same ip as 10 other people. but it has 100% confirmed stop my crashes, unplayable when i turn it off.
