Can someone tell me: Does FF14 has a rule to restrict player to get crystals and shards, if the level gap become too big?
As I already had written above, I killed on my way to my destination over 30 enemies levels 1 to 5 with my GLA Lv30 and not even a single shards adds to my inventory.
But just now I defeated a squirrel level 33 with my GLA and I suddenly got my crystals and shards.
Now I change to THA level 6 and killed a few low level enemies and I get crystals and shards again.

Does this rule always existed in FF14 or is it implemented since the latest patch?
I can't find any clarification about this rule on lodestone.
As you may already assume, yes, I just started to play FF14 recently and have no clue, if this issue is actually a bug or belong to the game itself.
