So many chests...and key's pffff, yup we must do something to get what we want. I have been a locksmith for 32 years and can tell that with an ax you can open most of them! If not just smash the chest! Time period, keys yes they can be old but most of the time people bury there valuables or had many creative ways to hide it. Pls. let me search for treasures and not for key's.
Most of the existing bugs are named "addressed" on the patch list. Fabric is one of the many and i still can find it so addressing is something else than fix/repair..... Addressing bugs is what we all do on this forum and see how much there still are and not fixed with this latest update! It seems we have to wait for a BUG RAIDING DLC!
