I want to report a bug. I imported my own map to be able to change its name. I opened it in the editor, used the 'export and test' function and went back to the editor mode again. Some things were strange at this point, like tiles on the wrong place. Afterwards the editor crashed and my map got deleted.
OS: Windows 10, 64 bit
Here is the file with the bug report:
