There is snow on the crates because it's the dropship for the snow map, people are warping there with snow on their shoes... The same as on normal Zone Iricia map
Apple was rejecting Graal Zone, so we were focussing on improving the card games, then they suddenly approved Zone... We were working on several different movement methods, will try to replace/make it an option what you can use. The official launch party for the multiplayer map will be on August 10 (if everything runs as planned this time).
