Hello!
I touched on this a little in my other thread in the main forum, but wanted to delve into it further here, since robot oil is in the HOL series.
i read a moneymaking guide here in the forums that mentioned making robot oil in Matras and selling it there. However, I have done this and I get a message when selling to the alchemist that I cannot sell this item. Based on what I see, it might be because it's a miscellaneous item, with yellow text. Did this change with a recent update to where you can longer sell this item in the main game? It won't let me use this item, either - when I go to my potions menu, it doesn't show in the list. It's a bit perplexing that it will let you make this item in the base game with the expansion enabled, but it won't let you sell it or use it in the base game.
Also, I see that permanent gush potions didn't make it through on HOL2. Will we be able to make them in HOL3?
Thank you all for this great game and expansions!
