I got an update on this actually!
This is a setting only in the Soulmart shop once you reach Level 121. The 5x items should be scraps - but are items (and accordingly, it's 5 times the price of the item).
This will be changed back in a coming update - so you will then be offered 5x scraps again instead of 5 full items. Sorry to bring the bad news to everyone that enjoyed buying stacks of Tomes of Occult Nonsense!
Single full items will of course still be available in the shop.
However the shop prices are still under review, and we are working on the token pricing overall.
There was also a lot of good feedback on the error (ha!), so I'll make sure to pass this on to our team so we can look into improving the rates for full items a bit.
Especially as Soulmart is one of the Token Shops that received a lot of scrutiny lately, we hope to take your feedback for this on board here.
