Apparently closing the cilent while it's updating (not patching) isn't a good idea.

The story is that, just today I logged into league, and for some reason it said it reserved the client version to the one before (so i had to re-update the client)

and the download got stuck in 63.42/63.48 (something like that) for a really long time. so i thought that, maybe closing it and re-openning it will do. and that choice ended up being a BIG N0-NO

as you can see, now i have to re-download shit again. oh well was gonna open the game to trade mystery skin with a friend so didn't really get into a lot of trouble, wasn't gonna play anyways.

but I learned something. never close the client during an update.
