Tower of fortune not every day and supposed hours to wait are always wrong ?

The Tower of fortune is not available every day and the supposed hours to wait until the next occurrence is always way off.Is this a known issue, or is it just me ? S6 - Location: Adelaide (AU)Since a few weeks now, after an update I suppose, the tower of fortune is only available every other day. When I play it and afterwards check when the next 'occurrence' will be, it says something like '19 hours' or. However, the next day (< 24 hours later)... no tower. It then needs another 13 hours or so. Basically I get it every other day.On that note, and possibly related, the daily feathers are far from daily either. PS. I try to play at least the daily challenge every day. That *is* in fact available every day ... without issues ...Go figure ?
