My custom multi structure bugs out

Status

Works as designed

Issue description

I recently tried to add custom mine to my mod.

It is made from 3 custom blocks

1. Mine Starter: Starts mine by X section

2. Mine horizontal: expands mine on 2 sides

3. Mine horizontal: expands mine on other 2 sides

Problem:

-Mine generates unstopably, weirdly and infinitely

-If you turn off procedure at block #2 or #3 it will stop hapening but mine will not be same as it have to be.

Included backup

Issue comments

If you don't make end condition that stops mining, it will mine indefinitely indeed.

I made end condition.

Every segment have 5% chance to be final one

Also sorry for late reply. I forgot I opened issue

If mine generates infinitely, the end condition is not working properly so I suggest you to debug from there.

It generates infinitely only when I set procedure for both block #2 and #3.

But if I select only one of them. Mine will end. So end condition work. I have other problem. My mine goes totally crazy. Thats what I am trying to solve.

also I just tried to load mod in 1.9.0 and I lauched world and my game crashed

Your achievement ShoppingTime2 is referencing item BoxOfCoins1 of your workspace that does not exist in the workspace anymore. Replace this icon with an element that exists.

Nice mod btw :D

What the heck. I deleted boxofcoins long ago and from that time I launched it more than 100 times. Thanks. I will try to also make my structure bigger segments so it can bug itself in

Yes. MCreator 1.8.3 did not properly delete some mod elements so such errors remained hidden until 1.9.0 :)

Okay. I tried to search for it but I can't find a procedure that causing it. Do you know which one it is?

It is not a procedure, but achievement/advancement. One of the does not have item/block defined.
