I have studied Blender for a while now, and I just started rigging and then this problem occurred:
The main bone is not connected to the main body bone, and I have tried to parent it to the main body bone to no avail.
P.S: This is my first post on this site so I have no clue how things work around here so forgive me if there is grammar/mistake in the question I asked, and please note that English is not my first language :D
