Match Accept/Decline Bug

I clicked the accept button and it said "match accepted" after several seconds, it said that I declined it and put me back to lobby. This has been happening several times and I've been dodging without my consent. It's really annoying. RESOLVED

EDIT: March 3rd, 2017 -- Riot has responded

"We're investigating reports of the client becoming unresponsive after accepting matches. We recommend enabling Low Spec Mode under Settings until it's fixed."
