I was crafting a staff (wich has ridiculous amount of time to finish) and i had to left the game for a moments. I've created other character when i log back and when i start playing with my main, the crafting machine says that i have not enough stuff to finish it. Am i missing something?

The craft if the staff is in a state of pause isn't it ? You just have to farm what is missing and continue the craft.

No dude, i had all materials to craft it, it was crafting when i quited. When i log back to keep the process the machine just said me that i don't have* the required materials o_o and of course there was no staff anywhere.
I want to play but if this gona happen to higher levels i don't know...

are you sure you did have all? maybe you looked on it wrongly as you are able to start crafting an item even if you lack some materials.

I am totally sure. Is for that i am worried to keep playing.
As i said, the staff was crafting when i logged off.

It's sad that you didn't post that in the right section (Technical issue) but perhaps an admin will read that before Queen Bee come back from her holidays.

Wow seriously? Does this only happens to me? well i think i have to wait to play, what sad.

I think i know what happened... do materials when stack in x amount transform into another one?
