The multi-line carousel works in build 6281, but there are issues with the scaling option in carousel.xc
This is how my carousel used to look, with a scale of 0.85: http://i.imgur.com/6sAvrUX.jpg
This is how it looks now, using the same config, with a scale of 0.85: http://i.imgur.com/bQ0sC3w.jpg
It looks as if the carousel icons are not scaled, and are covered up by the icons below and to the right (notice the last column).
However, everything can change if I click one of the tank icons: http://i.imgur.com/FN3re3q.jpg
The carousel icons are still not scaled though.
If I change the scale to 1, then everything looks fine, except I need to reposition my text: http://i.imgur.com/BAINuEE.jpg
I have attached my config for reference.
