Armature keeps spinning around root bone in pose mode when I try to move anything I was following a tutorial on rigging (was pretty much done) and now my entire model keeps spinning around the main root bone if I try to move any bone at all. (first picture is where it originally was and still is while in Rest Position, second image is of how it changes when in Pose Position while in Pose Mode or Object mode, Edit Mode seems fine)



I tried clearing All Transforms or hitting the ALT+g, s, r while all were selected and that just caused it to spin in the same direction like everything else does as shown in this picture:


I was nearly finished with this video tutorial here, 
https://www.youtube.com/watch?v=QbHAqk7OALw   and near the last part my issue began. 2:28:07 was the last time I was in edit mode and the pose was fine. Right after the little turrets he then went and parented 3 more bones and then he switches back to pose mode with no problem, I suspect somewhere in there is where the problem occurred on my end. I could have sworn I followed it correctly but maybe I went wrong somewhere I have no idea. 

I couldn't find another issue like mine exactly so sorry if this question has been asked before, I'm still very new.

Edit: I checked in the video comments to see if it had happened to anyone else but I did not see any mention of it unfortunately.

Edit2: Picture for more detail on the yellow lines.
This spinning effect many times is caused by an incorrectly set up IK constraint. Please check the Tutorial again for two things:


to which bone is the target of the IK chain parented to? The target is the bone which you actually move by hand. It must not be a child of the bone chain which is deformed by the constraint
what is the chain length in your IK constraint? By default it is set to 0, meaning the IK constraint affects every bone in the hierachy, so each bone which is a parent of the bone which holds the constraint. Try setting it to 2 for a start and check the deformation. Chain length is the number of bones which are affected by the constraint, including the bone which holds the constraint
