There's a bug in MIUI that's bugging the hell out of me (pun intended). When I use the Email app and register an Activesync account, sometimes the Email app completely disappears from the launcher. The program is still there; I get notifications and I can tell it's running ok, the icon is just nowhere to be found. I have found no other way to solve the disappearance than either a) clear Launcher data (and lose my carefully organized homescreens) or b) restore a Nandroid backup (and lose my SMSs and call logs). Also, sometimes apps disappear randomly, like when I was dragging an icon from the quicklaunch bar to the homescreen - poof, it's gone. The program is there, the icon isn't. Any ideas why it does this and how to fix it?
