A rebuild of Anvil Metal Recovery by Melchior, https://mods.vintagestory.at/show/mod/17
Rebuilt with .NET 7, and tweaked so it compiles successfully. I have not changed any logic or items. Only changes have been to update to .NET 7 using Microsoft's Upgrade Assistant (to update target from .NET 4.5,4.6,4.8, etc to .NET 7) and capitalizing certain method names so it successfully compiles with Vintage Story 1.20-rc6. It seems to work for me with 2-minute testing in creative mode. It seems to have not zero-summed my computer by dividing by zero yet. Bugs may abound, beware!
I haven't found any copyright or permissions on Melchior's mod page or in the source repo.
If Melchior wishes I will take down this ASAP as this is his/her project, just tweaked slightly and recompiled.
