nether roof?

[BudliCode]

Hi, i tried to search for a specific formation in the nether roof (3x3 with one on top in the middle)
command i used: java -jar bedrockformation.jar 5674239807397845618 0:0 roof -1,123,-1:1 0,123,-1:1 1,123,-1:1 -1,123,0:1 0,123,0:1 1,123,0:1 -1,123,1:1 0,123,1:1 1,123,1:1 0,124,0:1
However the result is always exactly where the starting location is.
am i doing anything wrong? or is the roof search not working? (search at floor in overworld worked great)

I know it's been sometime since this post but I'm having the same issue, I'm using the following command

java -jar bedrockformation.jar -6738937035815477756 -2015:-1555 roof -1,123,-1:1 0,123,-1:1 1,123,-1:1 -1,123,0:1 0,123,0:1 1,123,0:1 -1,123,1:1 0,123,1:1 1,123,1:1 0,124,0:1

And the result it always the same as the starting location (-2015, -1555 in my case)

having the same issue. command was
java -jar bedrockformation.jar 0 0:0 roof 0,123,0:1 0,123,1:1 0,123,2:1 0,123,3:1 0,123,4:1 0,123,4:1 0,123,5:1 0,123,6:1 0,123,7:1 0,123,8:1

Looking into it further, it seems the nether uses a different RNG than the overworld. This repo could help:
