yeah, I don't know if their ai has been improved since when this happened, but I was on a diamond level when endless mode first came out (0.2.0) and it was the level where there are 2 elevated platforms with spidertrons on top of them, and two spidertron-6000's just got tangled and fell of the side. they acted almost as dumb as humans =P
spidertron 7000-make it happen :)
