[HELP] Zero Editor Trouble

[Jango]

Last night i made some changes to my map and saved it, but when i opened my map today everything was completely out of place and needs rotating and all kinds of fixing! What could cause this and how can i fix this? UGH! every map i make messes up in some kind of way!
