[TCon API] Material ID 201 is already occupied by AeonSteel

[lightning02]

hello, i've encountered an id conflict when i've tryied to add tinker defence (addond for battlegear shields) on a private/local modpack.
I would have liked to open the tinker config file and manually resolve the id conflict, but i have found nothing even close to an id list.
there is something that can be done on your side or is there something that i still miss and i have to do?
i'm gonna report this issue also to tinker defence author btw.
