Map Problem Please Help

[domilol]

I get the error FATAL: Failed to create and object. Code: 477102

I think it is because when I opened my 8.0 map with 8.1 there were a bunch of void and random tiles. I fixed all the ones I could fine. Am I getting this error because there are more? How do I get rid of them all?

Try to open your map in another mapeditor and save it again.
Dont forget to make backups if it dosnt work.
