And again i face with this bug. Little help or even opinion is welcome

So. Today again i faced this bug. It showed my game version has been restored to last version and i had to download 73(aprox) mb of data and let it patch again. i am sick of it. Allmost every 10 times i open LoL client to play game(and i dont play it daily) i face this problem. My internet is fast too. 7,5Mb/s is fast. It's not internet or my laptop based problem becouse pretty avarage laptop. i think and i have no problem to say it. It's Riot problem. They launcher is just...bad. Extremly bad idea to use launcher. I could even make concept art for new fullscreen launcher who should not be as cancerous as this "new updated". Sorry for anger but this has been issue for a long time for me and propably others. This is by no means bad game apart from 8.12(i think). Updating launcher with new magic code and fixing bad performance in it would be very welcome. make patching as side process not part of client.

Also how do i cope with this problem? The launcher restoring to last version.
