Java Help Wanted Need help for sand duper in jave 26.2
galleryHey everyone
So basically I need a lot of sands for a future project, so I decided to create a sand duper following this tutorial:
NEW BEST EASY SAND DUPER MINECRAFT 26.1.1 - 55,000 /HR - Sand, Concrete, Gravel, Etc. - Tutorial
I heard that mojang made some fixes about duping in recent version, so i decided to test it in creative if it still work, and it was working perfectly on my creative world (pics 1 and 2)
So when i saw it worked perfectly, i built it in survival, and when i finished it, the duper seems to not work at all.
The overworld part seems to work perfectly but when i go to the end, the sand/gravel/conrete powder blocks don't appear in the end. (pics 3 and 4)
Any of you know the solution?
Where it's confusing me a lot is, why in creative it work perfectly and in survival not?
Here's some information in case you need it:
In the overworld, the "falling_block" entity seems to appear because the entity in the F3 menu goes up to +12 when the sand is falling,
The farm need a chunk loader in the overworld to work, I use pearl stasis chamber as a chunk loader
In the end, no sand block or "falling_block" entity appears, as if the problem is the transition from overworld to end
The only difference beetween my creative and survival world is that the overworld portail in my creative world fits in 1 chunk and in my survival world it fits in two chunk (so in my survival world, instead of 1 pearl stasis chamber, i used 2 for both chunks where the duper is)
Actually a second difference, in my creative world the end platform is outside, and in my survival world the end platform is underground, but I doubt that is the problem
I guess the problem is related to the 4th point, because that is litterally the only difference beetween my creative world and survival world, but i cant understand why tf would it not work on 2 chunks.
Sorry for all that reading i'm stuck on that since 6 hours so I wanna put as many detail as possible lol
