both types of ocean ruins and trail ruins contain no suspicious blocks of any kind
desert pyramids and desert wells do have their suspicious sand as intended

Still not working after the newest update.

Wait hold on, I accidentally had 2 version of the mod in my folder.

Testing to see if that was the reason.

prob still wont work, the processor is in 1.20 format and its process method is not being called at all

Also same issue here lol.

well, actually no idea why it doesn't work

Did you add any code that handles sus gravel generation in the trail ruins? Because I know that sus gravel in trail ruins is randomly generated and not saved to the structure files.

didn't knew it thanks for information!

it is kinda part of the structure file / specification
handled by processors

e.g. https://github.com/misode/mcmeta/blob/1.20.1-data/data/minecraft/worldgen/processor_list/trail_ruins_houses_archaeology.json

and you already have these
but it seems like you're missing the block tag minecraft:trail_ruins_replaceable
