Is this a test thing or is it real? If so what map and versions is this on?

So I'm planning on doing the run in a few weeks when I find time. Just a few questions:

1. For the solo run can we temporarily invite a player to pick up a diamond for the achievement. I don't think zombies can pick them up. The player will just join, pick up the diamond, throw it back then leave.

2. Can we take a break during the run because I doubt anyone can stand more than 16 hours of gaming

3. If I'm not mistaken there is a glitch where you can't craft a cake. I tried to for my noxcrew grid runner's world but it couldn't craft. If someone attempts this run can we get all the ingredients for the cake, put it in the crafting table to prove that it cannot be crafted then throw the ingredients into lava?

Those are just questions I thought of from the top of my head. If any of them are wrong just tell me thanks

Since there are 3 categories for each run, pc, console and mobile, it wouldn't make sense for someone with a controller playing on mobile instead of console. On mobile it's more difficult to craft items as you cannot do it as a stack, but currently you could just use a controller to get around that. The whole pain of mobile is that the controls are more difficult, so in my humble opinion controllers and keyboards should not be allowed on mobile.
