This is gonna be a short text, but it would do a lot.
Make it so you can’t see players, and PLAYER collisions are disabled whilst in the promo code area.
This would help tons of people out, while people are cramming into tiny zones just to redeem it.
While you say
“oh curb, your so handsome! but wouldn’t people just go into private codes”
they could, but new players might not know how, and will get frustrated.
this would help a ton of people.
