[Submission] Run Aground

[Sethja8]

did AI mesh work on the entire map (or at least where the bots should be going) and i think it works, but i can't seem to properly test it ingame so i'll have to go by gut instinct that i did it correctly

also fixed some texturework up, i still feel it needs more flora but that can be edited later

also, scene.txt and .sco updated
