Well I've lost not only myself and others LP
For seemingly no reason, the game launches like normal, but it remains a black screen and never lets me connect. Like any smart person would I eventually restart the client to no avail, repeatedly mind you. Nothing seems to fix it, and it only results in me losing a game and losing LP unnecessarily.
I would like the LP refunded for my teammates at the very least and ideally a loss forgiveness for myself. The error it gave me "once" for the several attempts I made to connect made literally no sense.
There are so many other errors I've had in the past, and they really need to be worked out. I can only hope that the new client will actually fix these bugs.
Checked my drivers, and they are up to date with the latest stable driver.
