Got an issue on both refined storages and refined backpacks, had an energy problem on my city today and because of that, the computer died mid-game, and upon opening again i found all my items, including upgrades, from the backpack were gone, and back at home i came back to my RS setup not working, all 3 64k item storage cards were corrupted, they were still there but placing them in didn't change anything, as if i hadn't put anything in, it was annoying but i moved on, only for the exact same thing to happen again hours later, idk when these issues are going to stop so i might need to avoid these two mods for now

Yeah this happens when losing power with RS, no solution other than backups.
