Unlocked Hats won't cause any crashes or anything, but if you accidentally let them use the colored cloth it will finish the production and nothing will spawn and your cloth will be gone. Just make sure your queues for any of those items don't allow the new fabric and you are good to go. I'll have an update for it soon so that it will at least spit out a product, though I don't recommend wasting your new pretty cloth on hats that can't have color changes

It was like WoW!! someone finally did it... thats terrific moment. I was hooked the moment I saw this today.
One question, Do you recommend I disable your Unlock hats at this time, or just be aware of any problems or issues ?
Thanks again, for everything

@Tasslehofph - Thank you! I think the most wild thing about making this, is it was just a random thought of can we change the clothes colors? while I was working on all the building mods. And wow was that a rabbit hole of an idea I am super pleased with the outcome though!

Let me be the first to congratulate you on what could be the finest most wished for feature in GM. Ever since I started this game I wished to have "Lincoln Green" caps for my Settlers. That Robin Hood vibe for all my outcasts and rebels who set out to start over away from Tyranny. Now for the first time you have given me this option. God bless you for all your hard work and patience in this fantastic project
