I made a thread elsewhere but was directed to here, so I will post my full experience here as asked.
I was playing Ranked Placements earlier in the day, did two games no problem. I logged out for a bit to take care of some things, about 3 hours I came back and there was a mini patch, did that. I went into ranked queue to continue placing, everything in picks and bans went fine, game started, I tabbed out to check messengers. I tabbed back in when the game still hadnt started and checked the loading bar, it was at 96%. I once had an issue with tabbing out before but it gave me an error message, so I looked and didnt see any error, so I figured something just didnt click and it was taking awhile. 3 minutes later I got an error saying "Game does not exist, feel free to begin a new game." It was worded exactly like that, which I found odd for an error message. The post game screen came up and it said the game was remade, but note that I never left that loading screen, so the game started while I was still loading.
The next game I tried immediately after. Once again everything was fine, what I didnt do was tab out. It loaded to 97% this time and froze. I figured something was wrong, but wasnt sure what I could do but wait. Seven minutes later I load into the game, because they didnt remake, but as soon as I right click the entire client freezes, and when I attempt to task manager, my entire computer freezes and crashes.
I reconnect after rebooting and find that it wasnt a remake but a defeat this time. I have no idea if they were able to remake or not, as I heard tale of a remake not being allowed, but nothing in the post game chat so I couldnt say for certain. Willing to give it one more shot, but this time, I brought a duo to tell me if the game started without me.
Once again, everything fine, until loading screen, loads to 94% and freezes. Friend notes that it takes awhile, but says in call when the game started. Hearing that it started, I disconnect the league client and reconnect. This time the loading screen only goes to 6%. I close it out and reconnect again, and again 6%. At this point they remake, and I am given a leaverbuster with low priority queues as punishment.
That details how it went for me, if you need any other details ask.
