Grottos not resetting?

route 3, route 4 (pls give d.sunkern i dont want to waste my d.sunflorite) ,crossroad and mount rose arent resetting for me, its been 3 days since they had an item/ pokemon in them.

Your hidden grottos are broken, you should ask in the trading section for the deltas that can only be obtained in them.

its because you may have changed the time in your system . its permanently broken (i think)

yea they get permanently broken, sucks because it breaks pokepon as well iirc
