Hi,
Welcome to the forum!
As has been stated by Tera, there is currently an issue with the yellow lotus potion.
You should use the potion of bestial memory as this will not remove any feats.
They attempted to fix the issue with the yellow lotus potion in the most recent update but unfortunately it was unsuccessful.
They have already acknowledged the issue as it was previously reported in this topic, so it’s unlikely they will respond here aswell.
This does not mean they have not seen your post, but they are aware of the issue already.
