White block gets a (clingy) new friend.

I have added a new block. This one is stickier than the first, and will stick to other blocks.

However, they don't behave quite right. They do prove that I can create fixed joints within gameplay though...

The problem with them is that two will stick together just fine. But if you add a third, they freeze in place in the world space.

Also, a white cube will stick to a blue cube fine. But if you stick a second white cube to the blue one, it will freeze in the world space, and the first white block will fall off.

I think I know why some of this behaviour is happening, but I'm not sure how I will fix it.
