I'm upgrading old CLOD missions, and wanted to update the Biggin Hill airfield, unfortunately some of the objects (blast pens, taxiway nodes) act as they were "grayed out" - i can see them, but I can't click them. Furthermore, I can't find them in the object browser.

I'm following this tutorial: https://www.youtube.com/watch?v=P-F3...pryYiM&index=2 He has his blast pens, and I can't find mine.

I'm using the Polish version of the game and the object names are in Polish. Is it possible that something was not translated, and the game cannot find it?

And how to switch to English, btw?
