Hi Sniperess!
Thank you very much for playing Alchemy Garden ^^, Yes! It is a somewhat funny bug, the tables are made of boards, so if you put an object in the space between boards, the game interprets that there is no table and therefore spawn a new item.
This spawn is because if you remove the table with things on it (alchemy table or mortar) with the hatechet, the objects become items so you do not lose them.
Regarding the updates, yes, I am working on a VERY big update that includes many graphics improvements, remodeled alchemy mechanics, a small town and the possibility of managing your own potions store to sell them to NPC.
I wish I could develop faster, but at the moment I can only work in Alchemy Garden for 3 or 4 hours a day. I have to continue in my boring office job to be able to pay the bills hehe. If you want to support me with the project, please add the game to your wishlist on Steam!
Cheers!
