in loading screen bug no reconnect option and said concluding game loading

Hi guys i want to report a game bug that happen to a premade friend of mine .... we entered a draft normal game 4 people premade ... in loading screen my friend got a report no internet connection while we still were communicating with a call program ( using the internet ) so he closed the league of legends and reopen it and the game for him was gone ... no reconnect button and he could actually choose play (options ) then he tried to see if he could start it and when he pressed start it sent him an error and saying loading concluded game ..... meanwhile 3 of us ( premades ) were still inside the game and we were looking at him like he was afk ( the loading screen still said that he were connected to the game ) he is not very good with the computer and i couldnt ask him for errors and stuff so i decided to make a post here about it....
