Hey! Those issues sound pretty frustrating, especially when you're trying to keep your gear in good shape and your base intact. Here’s a quick breakdown of potential workarounds and things to try:
Gas Masks and Shields Damage: This sounds like a glitch with the new patch, where items are degrading even when not in use. Until it's patched, try moving these items to different storage locations to see if it helps. Reporting it to the devs might also get it addressed quicker!
Items Falling Through the Floor: Since your base is above ground, this could be an issue with the game’s physics engine not aligning correctly with the base structure. You could try moving items to a lower level or different location until a fix is released.
“Unknown Location” Save Glitch: This seems like a harmless labeling bug, but it’s worth reporting if you haven’t already, just to be safe.
Furniture Sinking: This slow sink issue might be linked to the floor physics bug as well. Picking up each piece and placing it again, as you’re doing, seems like the best option for now.
