Runing game 0.0.72
When working on the bench to attach grips to blades, sometimes the weapon bugs into the bench and gets stuck. I find ths happens most frequently when the weapon reguires a guard. So its almost always the swords that get stuck. When the guard attaches to the blade, the blade is always attached to the direction the guard is facing and often end up stuck inside the workbench. Then the whole sword gets stuck and its difficult to unstick.
Im not sure how to attach the screenshot. Sorry.
Easy to replicate by attaching a grip to a guard ( so you know which way its facing) And connect it to the blade with the handle sticking up, and the connection site to the blade facing downward toward the workbench.
Others are having the same problem, it has to do with how the weapons snap together using the orientation of the part that you're currently holding with the right mouse button. Read THIS POST, it might help you avoid this problem until the dev can come up with a patch to resolve the glitch. Happy Smithing!
