possible bug? dont know where to report it

[putnamto]

i noticed that if i save a booster with a robotic part as a subbasembly then load that subbassembly it breaks the vab almost entirely, mouse clicks do nothing and parts in the menu's grey out, i can still click to drop the part.....but it doesnt drop the part it just clicks, and trying attach the part does nothing.

creating a new craft, and loading the sub with an empty vab breaks it even more, not allowing placing of certain parts(at random it seems) and not being able to left or right click with the mouse.

i dont know if this is related to the booster being the subassembly, or the fact that it has a robotic part attached, but it weirded me out. the video is uploading now.
