i dont know if its just me but whenver i try to merge the gear on the inklings it doesnt merge correctly and i have to manually apply it myself.

the lock on is the problem

As I said in the description, you must have the character in a T-pose, merge spine 0 and joint root together, then zero it, then rotate it 90 degrees and after that, attach all the correct bones

I have a question, how do the ears of octo?

No idea why the wristband is shown as error

Make sure that when you install the addon you click “Yes to all” when the error appears, if the error is there then uninstall the addon and re install it

On the arms of the female tank top seem to be mirrored as, if you manually merge the bones, the left arm of the character controls the right arm of the tank top and vice versa

How do I switch the colors?

@Novexus Nui 777, If you want it to switch the colors, Use the, Override materials. Then, find a colortint. Then, change it to what ever color you want, then you'll have what you want.
