Can you not craft because all your workshops seem to need repairing?
Do you want to help repair a workshop but don't know where it is needed the most?
The Wakfu Cloud website can answer all of those questions.
There is a list of all the workshops in each nation (Amakna, Bonta, Brakmar, Sufokia) on every server (Aerafal, Amara, Elbor, Nox, Remington). You can see the location of all the workshops (using the coordinates system on the world map, which you can see in the bottom right corner when you look at the map). You can see which workshops are repaired and which ones are broken. And if they are broken you can also see which resources are needed to repair it, and how much.
The lists are maintained by volunteer players, like me, so they are out-of-date once in a while. I have updated all of Sufokia's workshops on the Remington server today, and I'll be working on updating Amakna's workshops (on Remington, too) later today. If you want to help out by updating the lists, you can create an account on the website and then contact the website owner to get access to the updating functions. You can also help out by whispering me ("Zanwee", "Granny Grumps" or "Lady Zan") when you repair or donate to the workshops in Amakna/Sufokia. My account can't update Brakmar/Bonta workshops, sorry.
The lists can also mark some workshops as priority, meaning they should be repaired first of all. A very useful feature for governors if more people look on the website
