Thanks for sharing the finding!
There's a thread along the lines of a Guide to TDS Strange & Unusual? I didn't think anyone ever started one. I know people have reported goodies worthy of such a thief community traditional guide. Anyone up for starting one, collecting reported findings into one site/document, taking screenshots and videos in-game and in-editor, if there isn't a "Guide" somewhere already? One could hope. This is one of those things a TDS fanatic should've jumped to do already!
We have more engine exploit comedy videos and screenies than items for a Strange & Unusual guide, unfortunately. They're fun in their own right, but a lot of the same thing, like ragdoll slapstick and oil-slicks, Garrett floating, and AIs clipping terrain.
Ya know, I never tried the Kick the Pagan Sapling teleport bug, and don't know if the patch affects it. I also never climbed out of the game world through one of the few holes in the maps.
