Someone want to explain why my ability to chat has randomly stopped working, and no messages are going through? A chat ban wouldn't make any sense, seeing as how nothing's happened to warrant it.
I had the chat glitch one time, I was unable to write anything to World chat or in-game chat. Restarting the client corrected the problem.
It's a fairly common [client-server desync?] issue. For example, any time you abruptly leave the game (flash crash or internet crash) it seems to apply[100% in my case, not sure if it's as consistent for others, but most, if not all, of my regular adventuring companions have noted experiencing the bug at some point], lasting until you refresh once. It also happens sometimes when the game stalls out, similar to the 'hanging card' issue. Basically, when anything seems to be 'off' in Card Hunter, refreshing is hands down your best option to determine if there's an actual issue.
