I'm planning on changing my ign and would like to be checked to ensure I don't loose anything on packs that don't use uuid
Shouldnt have too many issues then. Maybe a inventory loss. Before switching your name make sure you have all your inventory cleared out. Most of 1.7 is on UUID so there shouldnt be too many thing
Regarding Name Changes | MineYourMind Community Islands/Botania/Thaumcraft/Thermal Expansion data, and Questing Data might need to be transferred. Baubles disappear, so make sure to put them into a chest beforehand
There are a couple things that may need transferred. If you are missing anything, create a ticket and we will fix it.
