When I throw an eye of ender it doesn't fly, which I think means there aren't any strongholds. I do have other structures generating. I am also using terraworldgenerator. I am on fabric 1.16.5. I also used chunk base to see where the stronghold should be but there was nothing there.

update:
when generating a normal world without using terra I can locate a stronghold, but it doesn't work with it.

I believe this is a matter of configuring Terra, so I would maybe ask in their Discord for help. They'll probably be able to give you instructions for making it work.

Additionally - please try with the latest version of Better Strongholds and YUNG's API. I've pushed out some updates that may fix your issue. If not, check out the Terra Discord to see what you need to configure to get it to work.

Were you able to fix the issue?
