[Single Player] /players command not working/showing

It worked perfectly fine earlier, but I swap between /players 1 and /players 8 depending in what I am doing. Countess runs you want a /players 1, but for big packs, I gobble that XP with /players 8. So what is going on?

I left a game, and went to make a new game and it’s bugged?

Having the same issue, was able to set it to players 8 but then I cant change it to anything else. did you find a solution?

Follow up, it looks like the command is working BUT the game as no ‘in game’ message after the first time you use the /players command
