Just did a solo qued rank match. Crazy tied, one team ahead in team kills by just a few, tied in turrets, when my team decides to all do dragon. As soon as we initiate dragon 3 people from our team get a frozen screen, and are forced to close out LoL completely and restart the client, giving the other team a good 5 minutes to push and win.

WTF is this bug?

Were they in the same room? Internet cafe? If there's a failure with their internet, they'll all need to reconnect.

no its happend to a lot of people(including me several times) hopefully they'll riot gives us loss redemption or something like that after they fix the bug

I have yet to see it on my team or enemy team.

working as intended
