So I'm trying to make tweaks to Pokemon stats for a personal rebalance project that I've been working on. Some of the stats stay after I've changed them, however others will not. For example, when trying to raise Venusaur's Sp Atk to 120, after exiting the Personal Stats window and reloading it, it has been changed back to 80. This happens everytime. Any idea why this is? Could it be that there is an inherent stat limit for each species? Or is the a random error?
