Hi! Hope you're well. I'm the most recent poster in the LuiAFK thread so I can't actually make a response. So I have to submit a bug report here, I guess.
Are you currently aware of any odd behavior from those "Gathering" chests? I have an Herb Gathering chest in the middle of my Herb garden (Daybloom, Blinkroot, etc.) and it says it's full even when there's a single herb in it.
I am miningcrack, a 21 year old german guy that likes coding and playing games, one of which is Terraria. I'll try to make or contribute mods for Terraria in the future. If you ever need to contact me I am available on Discord: miningcrack#5834 (dms are open) and Steam miningcrack
