Just once, I'd like to have an update where there are zero chat bugs. Is that too much to ask? This is a multiplayer game last time I checked. Typically, central to a multiplayer game is the ability to do this thing called communicating with other players. Update after update, new bugs to the communication system are introduced. It's painfully obvious WG either doesn't care, is inept in creating a chat server, or both.
I can offer only two solutions to this problem. Spend more development time on chat functions in the hope that you won't have so many bugs. Or perhaps finally get off your butts, realize that the KGB is no longer a thing, lift the veil of secrecy and use a test server.
