No friends?

Hi guys, not sure what happened but I have 36-52 friends but none show up as helper anymore. I use zeff to clear alvida elite and cannot be without friend zeff. At first I thought I overused them but after 12 h waiting still no friends, did I misplaced a wrong setting? At the moment every lvl gives me 3 guests to choose from all the time?

Never mind. Added some friends via code and they all appeared back. Might been bugged or something.

To refresh friends, you need to restart the app.

Actually, sometimes it is just that you have to remove or add one. Yesterday I had 2-3 not appear in either friend list or support during battle even after a restart but soon as I removed a really old one (18 days since last login) the missing ones strangely reappeared.

I hope I never hit that bug. My friends are too valuable. I got nothing but top notch leader as friends if I lose them all I will most likely rage quit!

Is it possible to re-add friends you've removed/denied, or are they gone forever? I don't have an extensive friend list (half Luffy captains). I don't have their codes, but I was removing/denying friends who didn't look active.
