Ok still managed to escape, just cut down on the number of elder guardians, it will stop the lag and give me the mining fatigue faster.

Still something to fix tho, the amount of elder guardians made the world lag, which caused it to not give me mining fatigue for a minute or so, and because the guard can't see you at that killcheck, it's a very easy way to escape.

I dont have someone to be a guard, so It was difficult to get into the cell...

That was the killcheck.

Oh frick.

Not being all; 'It was so bad, fix this fix that, blah blah blah,' just some helpful suggestions for you.

How I escaped:

1. I broke the bed.
2. I killed myself in the lava.
3. I respawned outside of the prison, and ran, literally that easy.

Ok, I escaped within the first minute of being in the cell.

Suggestions:
1. Block off the bed with a piston and a netherite block attached to a redstone clock, so the person will still fall through it
2. Cover the lava

Once these are achieved, it will be impossible to escape without smuggling items in.

Alright Guys, I'm going to give this one a try.
