I had noticed this when we upgraded the shard but the report was discounted and I avoided the issue by removing my grocery key from my master key so my key load macro wasn't hitting it. But with the loot bag addition I want my keys in my master key. So I really wish that this function was working as it should.
Tonight I tested this very carefully and verified it beyond a shadow of doubt.
1. withdrew 1000 apples from grocery key.
2. keyguarded the stack
3. removed one apple from the stack and then ate the one apple
4. loaded the master key
5. 999 apples disappeared into key.
Prior to the upgrade you could remove an item from the key and not affect the keyguard status of the stack. Now that apparently is not the case. Or the grocery key is ignoring it.
Kaw...
