The connection loss issue is related to playdota bots. I have 100MBytes fiber optic connection and I get dropped out only when using playdota bots.
The same problem didn't occur when using other host bots. The connection drops at random times in a game, sometimes I manage not to get dropped (only on funnymaps). In my opinion the host bot floods with packages because the connection is totally lost for 15-20 seconds. I don't lose my connection with eurobattle, only with the pd bot. So please figure it out, I think I posted @ 5 unban requests already.
