I tried to start a brand new file, but it didn't solve the problem...
Are you using build 1.1 or 1.0 (it's shown in the bottom corner of the main menu)? I might have an idea of what could have gone wrong, depending on which version you're on.
I am using build 1.1 !
Alright. We might hopefully have it fixed in the next update ^^
I will be waiting for it then ^^ Thanks you very much !
