:\ well it makes no sence at all, even more if the base was infact higher... also we can't confirm 100% that those were what you used since you yourself said you forgot...

i'm sorry you lost your items but i can't really say for sure what happened. not sure if any other alchemists are awake right now to say either but i guess you can wait and see if anyone else takes a look at your post and give their ideas... as for mine, i see you did nothing wrong here so you should not have gotten back a gold based item. I cannot tell what it was that you did for sure, unless you used a lower base or missed an item in the equation.
