Here's a solution to what to do with Pacifidlog- i was going to do this for a hack of mine, but scrapped the project months ago-
If things change after 5 years, why don't you make it a small island? The drought caused by Groudon could have had long-term effects on the water-based town, or something? It's pretty logical (for the Pokemon world), and really easy to map. Just an idea.
As for Fortree.. It'd seem like your taking the easy way out, but maybe a young child fell off of one of the bridges and died 3 years ago or something, so for safety reasons the bridges were removed and houses lowered. I dunno, just suggestions. As for that backsprite, i'll have it for you later today, AiiNZ.
