Interesting, I'll have to take a look at those spider walkers. Started tinkering with Hoth, for some reason it seems to be more forgiving to hacks than Endor is. So far I've given the Empire a snowspeeder and the Rebels an AT-ST, played it a couple of times and all objects still there, plays very nicely
Only bug I noticed was that Empire AI doesn't want to use the speeder of it's own accord, though the Rebels will use the AT-ST. I'm going to be focusing on getting other vehicles into the map now.
