The technical reason clash was cancelled
Just to clarify, what I am about to say is a rumor and I cannot confirm it is true. When I heard clash was cancelled for technical reasons I went and did my own research on why it was happening. According to Garena (the internet service that runs leauge servers in china) the reason why the clash was cancelled was because games would immediately crash while loading in, causing the game to be considered over and a random team getting the W. This is what was happening in China, I have no idea if it is the same in NA but it could possibly be true for NA
