What were you expecting to happen, and what actually happened
When selecting a chest to unlock using Minions, each minion based on their stats has a calculated unlock time displayed next to the Minion when choosing which Minion to task with unlocking the selected chest. The calculated unlock time for the minion should be the actual unlock time when the Minion is selected. Actually, once you select a minion for the task of unlocking the chest, the actual time to unlock is 7 minutes more. 2 examples below (1: Zappy unlocking Gold Chest; 2: Sickling unlocking Iron Chest)
How often does this happen? When did it begin happening?
Always; not sure when it started
Steps to make it happen again
Task a minion to unlock a chest.
