I've finished a Focus Tree on the old website. This one seems a lot easier to manage a Focus tree and i've decided to transfer the tree from the old one to here. To do so, i've exported the mod from the old website and on this one, created a new mod, new tree and imported the file and localisation to the new website. It doesn't import and it says "Invalid tree". What problem is this? Importing the Spanish Focus Tree worked just fine, but my old one for Brazil didn't, why? Is there a problem in the archives or the file names that causes this?

Could you link the old focus tree you're trying to import, and I'll look into this for you :)

Here, and thanks, my friend 

Managed to import the file, it appears you had a comment in "An industrial power" focus which prevented the import:

NOT = { has_idea = #a da grécia lá }

Unfortunately, custom icons are brought over by the import, so these will need to be re-added.

Any other issues, let me know!

Oh, thanks for that! I've added that cause it was a comment for me to remember what to fix later
