The reason was because not all the infrastructure for an actual battle was set up - this fixes it. It still has some strange text that appears though.
Also did some minor optimisations on the Vermillion Dock stuff - I think the direction I am taking Faraway Island will work. However, something in that script causes any and all special warps to crash in some way. I am not sure what it is that does it.
Added map data for Citrine City, including wild spawns, as well as a fly location. Also fixed an issue where Bill's Garden couldn't spawn wild Pokemon. Citrine is also green for some reason.
Underwater Tunnel is a new area that links Route 25 to Route 10, basically just being a straight tunnel needing Surf to traverse.
Also given Seafoam Islands and Lorelei's room an unused palette that gives it a more icy feel
