Giving a futa potion for the second time is supposed to undo the first. But there doesnt currently seem to be a dialogue option to allow you to do that.
This will be fixed in the next patch, sorry for the inconvenience. You can use the content filters (accessed by talking to your guide fairy, Rei) as a temporary solution to disable and re-enable transformations in the meantime.
Its not really bothering me tbh. I like the futa options. But good to know its on your radar. Is posting comments here the best way for sharing bug reports (if your not a patreon)?
