Ok, I just looked of the multi-bot, could have seen this earlier, and well as I look you are every generation changing the angle in aimdx or aimdx, in ties it works better if you use an angle from the tie, (*.fixang) that way the angle will be measured from the tie. You could also use *.fixleng so make set a lenght of the tie.
In fact taking aimdx or aimsx you're taking a little chance that it could go wrong, not a big chance but it could screw some things up. Sometimes the tiephycics just seem to need little to let it go wrong, there is an enormous lot of power in those ties, little movement could invoke a lot of phycics sometimes.
Maybe I am going figure out how it works and abuse it
For DB3, I'll implement some actual joints, so we won't have these sorts of issues.
Nice, he wait how does it work then in DB 2 the ties are connected to the bot and in a multibot the angle gets stuck after awhile. Well that has to need some kind of joint doesn't it. It is connected to some place.
Joint is place where it is connected, right. I could be wrong.
