Bug/Issue Artisan Goods Change Price When Unstacked

I noticed some weird inconsistencies in the prices of my artisan goods, so I did some experimentation and found that some artisan goods (Grape Wine is the one I tested, but I think it works for others) will change their per-unit price when you remove one (or more) from the stack without picking the stack up completely.

Here's an example. 8 Grape Wines, right out of the keg, would sell to Pierre for 2880g. That's 360g per wine, or 240g without the +50% artisan bonus. That's 3x the original fruit price of 80g, which makes sense, and seems reasonable for a 6-day wait.



However, if I take the stack of 8 grape wines, remove items one by one from the stack, and check their prices again, the price of each goes up to 600g. What a deal!



To help in reproducing the bug, I've attached a save file with a bunch of grape wines ready to be harvested and sold off to Pierre. To see the bug in action:

1. Grab two grape wines from their kegs
2. Wait until 9AM, then go into Pierre's shop.
3. Check the price of the stack of two wines -- should be 720g (360g x 2)
4. Exit the shop window, open your inventory, and break the stack using the 'use tool' button (not the 'interact with stuff' button). Place the separated wine into a different inventory slot.
5. Check the price of each bottle of wine -- the one from the original stack should still be 360g, and the one you removed should have gone up to 600g.

 

Whoa! You're amazing, dude. This game rocks and so do you.
