I'm going to be absolutely clear on this for troubleshooting purposes.

- I have Nirvana ZETA in my inventory when I speak to drake.

- I can ONLY purchase the Nirvana Zeta replica when I speak to drake.

- I want to purchase NIRVANA replica - the step BEFORE Zeta.

- Googling tells me I need the completed relic in my inventory in order to purchase the previous stages. I have it in my inventory already.


What else could be causing this issue?
