Client crashing while picking and while in-game. Also, Minion Dematerializer disabling remakes.

How are these bugs not fixed yet, it should be top priority. It causes unnecessary LP loses, how is that still happening, I don't even see a notice in the client addressing the crashing problems like in the pre-season.

I've had 2 unintentional dodges and 2 4v5 due to these problems in a single day. And for the record, I don't have a low end pc, so it's definitely not that.

EDIT 1: I'm not 100% sure if the remake bug is related to the rune, coincidentally, it was the case for me twice, so I'd assume it is the rune (Minion Dematerializer) what causes the problem, maybe because the game considers it as a bought item. I'd like confirmation about this.

EDIT 2: Another important bug causing LP loses is reconnecting, I had two games in which an ally disconnected for a short period of time, definitely not that long, from 1 to 2 minutes, and it still made him lose LP, as if he was AFK. I also would like more cases like this as proof. (Maybe this is intended, if that's the case, I think it's too little time for such a punishment, specially if the game was won).
