Cannot Craft Medjay Predasite

[Scarletwing]

I have tags but it shows I don't and won't allow me to craft.

To revive a infested pet, you need to capture a weakened one, not just have a tag. It's misleading in a way. You need to find one that's been attacked by the infested first, and then call to capture it.
