Yeah that happened a lot because of a spectator issue. Whenever someone died (not when someone attacked and/or killed them but when they fell off) they would become a spectator. They could kill other people and not be killed and not be able to win the game since they died or break/place blocks. @KvixSi that also happened for some people as a glitch. I think both were fixed though
, if u like my suggestions and feedbacks. Life is unfair fr (the winstreak thing wasn't even my main concern, Ammsplay brought it to me. The idea of making it a suggestion was mine though).
