lets hope is an unintended mistake that came with the last patch and gets fixed asap.

medium threads are in grocery store for MOON SCROLLS (not sun scrolls, that are way more limited) and the reason why you get all those moon scrolls from SA is exactly that, because SA doesn't grant anymore medium threads.

Up to 4.0 SA expert mode dropped 1-3 medium threads and 1 advanced thread, when grocery store was added they were replaced with moon scrolls.

You don't need that many medium threads to hit level 6 BA but you need an amount 10 times higher to do anything with charms and advanced refinements.

So, if you don't buy medium threads in grocery store with moon scrolls and instead you only go for cave keys it's exclusively your choice, if you played when I began to play you had not that choice.

very likely was an unintended mistake. lets wait and see, is not the first time it happens.

They never fail to amaze me in how easy is for them to go back on their word.

Does it seem to you all it was specified that was a once in a lifetime?

To me no.

EDITED: seemed a bit too harsh, no reason to do it from me.
