I have 7 days of material storage left, so I purchased 90 day material storage ticket from SG shop. However when I tried to use it from inventory it says
"The item is currently unavailable because the period of validity has surpassed 90 days. Select 'rental expiration' from the Main Menu to check extendable validity period."
When I checked the rental expiration menu, it seems to force me to spend SG again to extend for only 1 month, so I haven't clicked it. How do I use the 90 day ticket?
