Hey, we are now completely overhauling the save system in the game. To make it work properly and not impose more breakages.
In the next version the transfer system will work in such a way that the potion has to be placed on the table, we had to roll back the game version to fix the bug with frozen visitors in version 0.1.05, however the text to transfer the potion is still new. Therefore, this may cause misunderstandings for players.
Regarding the additional hint, we will think about how to make it clearer, as we thought that the hint text says everything.
