Could not pass event SBASpawnerTierUpgradeEvent to SBA v1.5.6-SNAPSHOT

I get in the lobby, but as soon as the game starts. I get kicked.. Note that im on paper 1.7.1 build 278. Ive tried with both Screaming BedWars version 0.2.18 and version 0.2.19. Still the same problem
Good luck on fixing the problem!
