It's a compatibility problem. I should ask both sides.
The issue in the other side is more complex so that I wrote it previously. It is for sure that the details will be detailed.

This was mentioned in #7. I had a look at InventoryProfilesNext's code and couldn't really figure out how to add the blacklist automatically.

If there's a way to access their config via code that could be solved on either side but the simplest is a manual blacklist of "minecraft:spyglass".

Maybe juancarloscp52 can add an FAQ to the mod listing page to say to manually add the blacklist? (and this issue can be marked closed/duplicate/wontfix)

I'm sorry for my neglect. The issue can be closed.

Maybe it IS necessary to add an FAQ.

But it is strange that the problem even remains after putting "minecraft:spyglass" into blacklist manually. Please don't forget to ask them to "reload rule files" as well. I forgot it so it didn't work. How Silly I Was！*Laugh*
