To be clear: It is being tracked from fishing nodes, but Rarity does not support two different methods for a single item. Therefore, the NPC being killed will not add attempts for this item despite being able to drop it.

This could be resolved by adding custom code (similar to the various world objects/chests) for fishing, then using NPC mode in the DB. It's not very elegant, but it's also easy to implement via copy/paste. A better (more advanced) option would be to also allow a table value as the method field and then iterate over all methods. However, that might cause issues depending on how the other fields are used?

I also just noticed that the Strand Crawler pet isn't tracked either. At some point, it was, though, as I still have an abandoned entry in my saved variables... weird?
