I modified 2 machines because I felt I had not gone far enough, and it is now done ! I am talking about the Concentrated and Shiny states, which were not really taken into account on these 2 machines.
Bug fixes :
The save system.
Steam achievements related to a MonsterCoin amount no longer require the tab to be open to work.
Bonkers no longer Bonk 1 ingot if the visible ingot setting is above 50 (as this does not represent 2 full ingots).
The crafting menu translations are up to date.
When a resource enters a smelter, it sometimes creates a duplicate in another smelter that has an empty inventory.
Changes :
Fusion furnaces now save the number of Concentrated and Shiny ingots in their inventory and, when the inventory is emptied, they return the correct number of ingots in the proper state. Note that they consume Concentrated and Shiny ingots first when creating alloys.
Bonkers now take into account the number of Concentrated and Shiny ingots during bonking. If at least half of the ingots are Concentrated and/or Shiny, the new ingot will receive the Concentrated/Shiny effect (and therefore can no longer be concentrated or cleaned again).
