Sometimes, in Haven - usually at least once or twice every half hour - I'll press a key when talking and then it will just spam that key, endlessly(sometimes even a sequence, like / and then enter, so if I hit enter to type it floods me with the / command list), ie just going "mmmmmmmmmmmmmmmmmmmmm" every single time I hit enter to speak, or try to type anything anywhere. It then stops for almost no reason at all, at random.

I have no macros or funky background stuff running, and I'm playing the Steam version. I would very much like this to stop.

Also, in case it isn't overly clear - this ONLY happens when I'm in Haven.
