1. There's now an option to vote for the custom maps (the Terra + Iikka "episode").
2. aguirRe taught Orl how to preform some kind of dark magic ritual to re-vis the Iikka maps so that they now have properly transparent water, and this also resulted in improved FPS performance.
To get these benefits, you should re-download the Iikka maps from our website: http://www.fvfonline.com
