Firstly, This Mod is an amazing mod and makes every part of play through so much easier, saving hours of organisation and looking for items, and it is relatively bug-free, but I have seemed to encounter a rather large problem which may or may not be caused by the mod
Too many items in one chunk I believe.
after a few days of the playthrough we had accumulated around 2000 various items in one main storage system near the spawn of the world, however this seemed to cause a large area of the world to disappear and bug out when loaded on any kind of multiplayer, despite the world being there fine and working on single player. this was remedied by moving around 100 items from the main storage system into a secondary storage system a little further away from the spawn,
other than that, a great mod with very few problems
