Update coming! Brave testers needed!

Some objects in new editor lose its geometric parameters.

Is it your own model? I suspect it has the wrong unit scale in the dae file, which the old version of the game didn't take into consideration.
Open the file in a text editor and search for a line beginning with "<unit" (without quotes) and let me know what it says, or send me a link to the file in question.
