Today, all I did was open up my mod (with custom armors and weapons, using some vanilla and custom meshes/textures) and I changed the armor rating on some of the armor. I opened up the game then, and now my armor is invisible and has no armor rating (all of the modded armor, not just the ones I edited). Not sure what's going on. I changed nothing else at all. The weird thing is, it's just the armor. My modded weapons work just fine. Anyone have any idea what's going on here? I'd revert back to a previous version of the mod, but for some reason it didn't save to the backup folder when I saved it that one time.

It's a creation kit bug.... it's been confirmed by several users in this forum already. I hope you have backups, not sure if it's recoverable or not via another update from Bethesda.

Do you know if there's a way around this bug? Or is it just completly unsafe to mod stuff right now until Bethesda fixes it?

I haven't found a way around it yet, just opening a mod and saving it using the 1.6.91 creation kit causes the bug.
