Never seen this before in my match history. What's it mean?

im wondering that too!

It has to do with technical failure. Sometimes you'll get kicked out of a game because the League of Legends servers are being work on, updated, etc. Instead of getting a loss for this game, it'll say Loss Prevented.

Sometimes you'll get it anyway, even if you weren't kicked out of that game. Just take it as a free game, were the loss didn't count.

I suppose they changed it after the fact, because the stats screen counted it. Interesting!

If Riot's servers decide to start having problems, and people start to dc or game start freezing because of their servers, they will decide to "Enable the Button" which means if you Lose a game, then you get a Loss Prevented. This usually only happens when the Riot Severs decide to be stop being good.

Oh okay that's good to know, I was confused when I first seen "Loss Prevented"

Thanks!!

when loss is prevented

so does this count if someone on your team DCs from server failure too?
