So when I play in my solo world, everything works fine. This excludes the fact the the right side of the top row of my inventory is inaccessible. I cant even hover my cursor over the slots. This is a problem because I end up getting materials I need into those slots, and then I cant get them out. I have no clue why it's doing this. I just uninstalled minecraft (after taking out my worlds, texture packs and mods) and reinstalled. I then put everything back where It was and the problem persists. Any idea how to fix this?
Edit: I think I fixed this, but I'll leave it up in case someone else has the same issue. If you click the world from the world select menu, go to edit world. then just click the "optimize world" button and go through that process and it should work fine! (Note: this is on 1.14.2)
