Is it just me, or is there a problem that if I start recruiting pirates in the tavern, and then close the lid on my iPad (to lock it), when I "return", there are no newly recruited pirates... Happened three times this morning!
This is a bug that is known by Midoki and they are trying to fix it. In the meantime give it some time before you lock your iPad! That prevents the bug from happening (for me)
Try to stick around and wait for just one pirate to finish training. I've was getting very frustrated with the same problem but that has fixed it completely. Still annoying though!
