So basic really it crashes anyone on a server NEAR BY where the firework is placed. The 3x gunpowder + paper is what method I used. From what information I have gathered I found out that ANYONE WITHIN 64 blocks will receive the error message "End of Stream".
I created these from scratch AND spawned them using "gamemode 1" environment.
I checked the server.log but there are no useful information there.
