Well, since the last update, there have been glitches that the legs when copied, are not in one. They're considered one when moved or copied, though, so not quite yet... Anyways, most people have been thinking it's only a glitch, but it's not... The design for it taken apart is identical to real life... And, if you copy it twice, you can make a leg fit to another waist... I'm pretty sure this means they will allow you to give it to peg legs, or a peg leg and a robot leg, etc... This also goes for torsos... There was a similar glitch with that. Haven't you always wanted a two-armed robot in LDD? Soon you may have it.. I'm quite happy about this, as I've always hated we weren't allowed to do this in LDD... This is a new era to LDD! We must know it!
