When you fight with monster and you try to deconstruct item with invention cube it says you need to be 10 seconds out of combat before you can do it. When you killed the monster you can use it instantly, no need to wait 10 seconds. Before you could deconstruct items while combat, this came in todays update?

Works fine for me
