The server crash does not result in the client getting a red chain and the message that there is no connection to server. You can run around on the map for hours but you cannot interact (ie. rearranging stuff in inventory, drawing a weapon or putting it back).
Despite the fact that Bohemia is closing tickets with this issue like ticket #0017124 the reality is, that this issue is still there. No matter how often you say that it is not.
