Not
stuck, but collision problems. Some of the tree clumps aren't as solid as they could be:
Also, I found a collision problem with the hill that the tower sits on. Start AHII, take the default field, fire up an M3, and drive out of the hangar. Angle right to go up the hill that the tower sits on, and drive along the right side of the tower, where you'll find yourself on a concrete path heading down off the hill. Angle a little left so that you're on the grass to the left when you reach the bottom of the hill where the concrete path crosses in front of you, and your M3 will come to a sudden stop. After you stop, you can continue driving in the same direction, but there does appear to be an invisible collision plane there. The problem doesn't seem to exist with other hills in the terrain, but is reproducible on the tower hill.
It's just a matter of taste, but I don't think that the little vegetation bitmaps -- the ones that look like clumps of grass sticking up, and are about 1/3 as high as an M3 -- should be 'solid'... there's not enough there visually to justify taking an M3 from 50mph to a dead stop instantly. I don't know if it's possible in AH2 to single out an individual type of ground clutter to be intangible, though.
