The following map causes several error messages to appear on load. Messages are about wrong names (i.e. isdemo instead of is_demo).
The map was generated in previous version (in this thread).
Then it was edited by me in current redactor and saved as copy. Original version (map itself) loads well, edited version triggers error messages (but thankfully works).

The errors you see in your updated version of the map (TheCity_0.12.0.zip) are just old messages saved in the console history, they do not appear when loading the map. There were probably some errors when you converted the map with an old version. When I convert the map now, it seems to work well.

I know trying to make a custom map like this is very tricky and not well supported, but I will mark this as not a bug.
