Talk: Fake Vent Cover

I waited on even making these based on the wiki entry (since there's no manual and the in-game F1 is 6 lines long) until I had a screwdriver, intending on using the fake vent covers for those vents I rarely access and a screwdriver to remove/replace a 5% durability true vent cover (less durability per entry/exit with the screwdriver setup, and removing a vent completely without a screwdriver removes the option of using a screwdrive-able cover). However, since using the fake vent cover, it has lasted far longer than the quoted 5 times (20% durability per use)...in fact, I don't even get a durability pop-up on it. Did they upgrade this to be comparable to the poster in a dev update, or did I manage to build a bugged vent cover?
