Ohh, I see — yeah, you're correct, I just made a mistake with the import. Thanks! This new system looks great.
What happens if you have two STMAutoDelayDatas pointing to the same char? I've always wondered how best to manage this. If I edit the delay values in the files in the STM folder, they'll get overwritten when I update the asset, so it seems better to duplicate them and keep my own copies — but in that case, should I delete the originals in Resources/STMAutoDelays?
