Bug: A simple var-editing typo can make maps unreadable

[QuiteLiterallyAnything]

Version

v2.14.2.alpha

What happened?

Apparently, while editing a map, I forgot to include a quotation mark at the beginning of a string variable on an object:

The next time I tried to open the map it was displayed as blank with dimensions of (0,0,0):

This led to quite a bit of confusion until I was eventually able to figure out what was causing the error while attempting to commit the map:

Reproduction

1. Run StrongDMM.
2. Var-edit a string variable on an object and don't include a quotation mark at beginning of the variable.
3. Save the map, close it, and then try to reopen it.
4. Your map will now be displayed as blank with dimensions of (0,0,0).
