Unsurprisingly, I completely disagree with you.Completely disagreed. While you do have a point that some games require updates, I honestly think all games should be playable without bugs first.
But then again, this seems like it'd be a problem between server and client together, so I'm not sure about this being fixable on Cube's end or not. Aside from that, I rarely have this happen to me.
But again: Bugs should be fixed before updates are released. That's the way to handle minigames in my opinion.
The system the almighty CubeCraft have right now is very good; ignoring the bugs in pvp (such as this hit registration glitch), inconveniences in games (cannibal in SG, kb shovel in speed eggwars, build limit in no projectiles skywars etc), and creating brand new games/updates nobody asked for.
This is the current method and I love it and I'm sure everyone on the server loves it too. Little bugs like this don't matter, because if the developers focus on legendary games such as archer assault, bingo, freebuild etc, then its all forgiven for as the community clearly loves those games.
