"File" menu unavailable after changing unit orientation

[kurt751]

(Version 1.16 on Linux)

To reproduce, open the editor, load any scenario having units, right-click on a unit, chose "change orientation", select some other orientation. Unit changes orientation as expected.
Now, click on the "File" menu button - The game will think about it for a second, then vanish in thin air.

Tried it on several different scenarios, from huge ones with hundreds of units to small test ones with 3 units on an empty tiny map.

1.16 will not get any solutions.

I guess not, but I thought I'd report it nevertheless.
