In addition to the the fighter fuel IV issue, you should also look at the movement data for forest pine mud and forest pine loaf. They are inconsistent with each other (for regular they are the same). For example, for forest loaf mud, wheel has a movement of 9999, while tracked is 80. But, for forest pine mud, they are 50 and 40, respectively. I am guessing they should probably be 80 and 80, which is what I changed them to in my graphics mod. Something "minor" to fix in the next release as well.
