I have an idea, I do not know if it's worth it, but maybe I would solve many ideas problems for tpt, like burning elements only if I have oxygen, my idea is not only to use a one version of tpt, but several versions of choice for the save, so we would not lose the old saves, I do not know if it's worth it, if it's difficult to implement, but could it solve those problems? (i am brazilian, sorry for bad english)
