Odd Black lines

Hello Everyone! So since modeling this character these weird black lines have appeared and I am not too sure of what they may be. I did hear that this maybe cause by overlapping geometry but I do not know how to fix that. Thank you for your time.

Hello, maybe share your armature: https://pasteall.org/blend/

It’s ok I found a solution to it, thank you!

Good evening, @JesusC! Would you mind sharing what your fix action was just in case someone else ends up with the same issue in the future? Thanks!

Good evening! It was rather easy but time consuming. So basically I followed these black lines to the duplicate vertices. I switched between edit and object mode to see where the problem was. I hope this helps!

Ah, so the black lines were edges from vertices that had been moved or extruded from your model. Got it! Glad you figured it out! Thanks for sharing!
