Crated alt character. Completed tutorial. Swaped to main character. Eve had quest for me. Picked it up. My oven stopped working. Blank space. Switched back to alt, made first steps of quest with oven. Then swaped to main character. All event materials was gone. All of it. It was like 7h of grinding just for materials. That's few days for me, because of work. How can I get back my grinded materials?
