Hi Astely, is this something your team could help take a look? suspicious bug in the above range?

I will check it tomorrow. (keep ni)

So far, what I found is, sAliaceDisplayItemDatas was deleted right before crash, which means _all_ DisplayItemData objects are destroyed.

Given that the crash rate is quite low for now(5 counts in 1 installation), let's leave it for a while and see what's next we can do.

I don't see any crashes after 20170607030206, so I think we can close this one out as WFM. Please feel free to reopen if the crashes reappear.
