Sorry! I hadn't hit save on the page after uploading the new files. They should be there now :)
Thanks!
Sadly I actually tried to reproduce it on the old build before trying the new one and didn't manage to.
So we'll just have to wait until someone else steps on it if it's still there.
I didn't say but I'm playing on Linux and the issue happened for me at level 8 since I adjusted the setting to better face the duck.
