Check for new chapter bug

[hellomynameisleo]

Having 400 mangas added to the favorites, and auto checking chapters every 20mins. FMD when checking for new chapters will sometimes bug out randomly and at the current chapters will always show "0" on all the manga on the list and won't be able to fetch new chapters until FMD is restarted. Any idea how to fix this?

Can be anything, from connection issue or server problem. More info needed, like on which sites that happens?
