Plains Pebble changes???

[guineapig]

I was trying to find a post regarding changes to plains pebbles but can't seem to find anything.

For the past 11 months or so they were stackable. I had bunches of them saved up in the bank for eventual cultural armor use. Last night I foraged 1 only to find that it's no longer stackable. I checked my bank later to find that instead of nearly a full stack I have 1 in my inventory.

Was this intentional? And if so, since they are not lore, shouldn't they have at least ended up on my cursor when I logged in instead of going poof?

(If this is a bug can I get my lost pebbles back when it's fixed? It took forever to get as many as i had.)
