I thought the risk was the reverse, that if I post on something extremely similar the mods will just say I need to look in those threads! I looked in the FAQ, didn't find anything quite like this though. I will make a separate post.
Seems all our issues were caused by downlords client. Now we both use official client and so far everything works fine. You may mark my topic as solved
Well with original client i never had a connection loss to all players, with downlord his client in game already 2 times i lose conn to everyone while i am still in lobby and still can internet. This is weird. Not gone use the client anymore.
