Yes I do, for example the cryengine was nerver designed for legs with more than 1 knee joint, what is causing the regular crashes with the novacat. And that is only one example. No one did things like we do with the cryengine yet, so we often hit heavly untested code. But if you have better knowdelge then me about c++ and the cryengine feel free to join the team and fix all the bugs.
