Got 4 joint textures but when i activate them they say they are, but then i go check activated and they're not there, as they still are deactivated,

tried redoing it manny times now but nothing happens.
-----
Now i tried to see if i can deactivate something activated and activate it again. but now nothing wants to activate.

What message does it give you when you click on "Activate"?

You might try a different browser.

The only thing that shows any sort of message that is different from what usualy happens
is the head texture. Shows up a yellow message saying ''This texture conflicts with texture Head Texture and was deactivated while activating this item.''

And i don't have any other head texture item in my inventory.

Anywho it worked using Another browser.
Seems it doesn´t work on Microsoft Edge but it worked on Firefox.

Good to hear.
