Yes, GOTR adds too many new options, far more than the game is programmed so support, so it removes a few options to make room for the new ones.
Yes, you'd have to mess around with customization_items.xtbl, easiest way to do it would be to find it in customization_items.xtbl in modified folder of GOTR and adding all relevant lines to vanilla customization_items.xtbl
Thanks for the clarification, that makes a lot more sense now

I just wanted to share my specific case in case it helps confirm the behavior or if there’s any workaround:
I have a
save that was originally created without GOTR, where I had
Tribal 11 purchased and equipped normally from a tattoo shop.
After installing GOTR, the tattoo
still appears correctly on my character, but it
no longer shows up in any tattoo shop, so I can’t reselect it if I remove it.
What I found interesting is that
Tribal 11 itself looks reworked / improved — the model and texture seem cleaner and better defined than vanilla, which made me wonder if it’s being overridden or remapped internally rather than fully removed.
Based on what you explained, I understand this is likely due to GOTR removing some entries to make room for new ones, but my question is:
- Is there any way to re-enable Tribal 11 in tattoo shops while keeping GOTR installed (for example by editing tattoo.xtbl or store_inventory.xtbl)?
- Or once GOTR removes it from store inventories, can it only remain if it was already equipped in the save?
I’m mainly trying to understand whether this is a hard technical limitation or something that can be manually restored without breaking the patch.
Thanks again for the explanation and for all the work.
