After applying oil I was gathering rock. The oil timer was not counting down by seconds. It was actually knocking off multiple seconds with every swing. After gathering for approximately 4 minutes I only had 30 seconds left on the buff. I tested this with weapons and multiple other gathering tools.
Please provide a step-by-step process of how the bug can be reproduced. The more details you provide us with the easier it will be for us to find and fix the bug:
1.Apply the efficiency oil to a gathering took, in my case a pick axe
2.Gather items, in my case rock
3.Watch the timer go down 5-10 seconds at a time and not count down in real time
4.Get upset because your oil falls off twice as fast as it should
