I definitely have the required memory I have 4 GB of ram, 3.86 usable. And it's not stuck on saving it's stuck on Finishing, I tried it again with a new map that I made and it did the exact same thing, so this is a total of 5 times now it's done this, also, sorry about replying so late, I didn't think anybody would help me after going away for a couple minutes. and it's stuck on Finishing, not saving.
