I've been using a custom modpack (modlist here > https://pastebin.com/VijaCMYs) for around a year now. Suddenly after searching for an item (in this case, antiblocks), it seems that my tablet has become "stuck", in that now only a few items are able to be taken from it (charcoal, antiblocks for example). I can unlearn any of these items and that part works as normal, however if I unlearn an item that is no-longer present (ex: diamond) and relearn it, nothing changes (but the tablet claims that it unlearned/learned it). This is especially an issue as the game is rather late stages and I had the majority of my storage based around the tablet. How would I go about fixing this?
