I was the crafting-tester in the past, when it was implemented.
I have checked to crafting just a minute ago and found following things:
Melting Ores does not work correct.
I placed some Ores in the furnace and the server told me, that I am working on the Ores.
After 5 minuts the ores are still not changed to Molten Ores.
I tried to make steel and the server told me, that i am working on the Ores.
After 5 minuts the ores are still not changed to Molten Steel and when i reload the screen,
i end up with Steel Sludge.
I placed the Steel Sludge in the furnace to make Molten Steel and the server told me, that i am working on the Ores.
After 5 minuts the ores are still not changed to Molten Steel.
When i try to heat Stocks, i get the message: "You probably should not leave ............ here"
Without a working Furnace and Forge, i can't test the rest.
Conclusion: Crafting items is fully down atm.
I have sent my report to Tomt, by addding it to my bugtracker report:
