Which bugs are you talking about? The slaving crosstalk bug. The rendering bug when extra Weld commands are text-edited in. Omitted Weld statement causes a morph bug. And most of all:- Getting its trigonometry sums wrong when converting an IK-goal's coordinates back and forth between IK-on and IK-off modes. This shows most whe the IK-chain is of several members. And cases when the result is "correct" but bad, such as it working out that a part is xrotated 372 degrees instead of 12 degrees.
