Summary of the problem Items vanish off of a 64K disk drive. Refined Storage Pack Version 1.0.0 What is the bug? On single player. Set up a refined storage system, was working perfectly one day, next day all my items were missing, close to 8k. Looked at the 64k disk that the items were stored on, the disk is still 12% full telling me that all my items are still there, but I can in no way see those items on a monitor or access them in any way. I can place new items on the disk, filling it up further and can interact with those items just fine, but not the ones that were on it previously. Mod & Version Refined Storage 1.2.4 Link to log file Is it repeatable? Unsure. Known Fix None that I could find. Tried to replace every part of the storage system, didn't work. Tried to load the disk on a completely separate refined storage system, didn't work. Tried to empty out the corrupt disk onto another empty disk, didn't work. Tried to drain out the power from the network completely, didn't work.
