Any idea when lists will be unbroken?

Hey, I have a collection list with 304 items in it that hasn't been updatable in a month. Was curious if that issue is being actively fixed right now, whether it's an issue with all lists, lists with 300 items in them, or specific old lists. It seems like an issue when it goes to update where it stalls at the saving part before saying "Something's went horribly wrong."

Please tell me when it does get fixed! I have a few dozen games to add to it since early May. (I got an iPhone for the first time ever last month, most of them are iOS apps)

List are actively being worked on (by @ltsquigs). Hopefully a fix right after E3 as we want to focus on stability right beforehand.
