In short, there is a pie chart you can activate by pressing shift + f3 in minecraft. There is a way to find buried treasure without a map, known as mapless, using this pie chart. When using the create mod I don't have a spike and there doesn't seem to be a way or a known way to make it work. Here's a video showing how mapless works in 1.18, https://youtu.be/wb8wBzmwWnU , and I hope I can do this or fix this in some way because of how useful it is. (I did test with only fabric API and create, and there still wasn't a spike, so the issue is 100% create.)

Issues for the Fabric version should be reported on the Create Fabric repository. However, Create does not interact with treasure chests at all and even if it is somehow Create a spike is lag and increasing lag is not something the developers will want to do.
