Daylight savings time seems to have caused some players' Towers (among other things) to not reset. Shop and dungeon refreshes and PvP reward collection times are also affected.
In addition to making people miss out on a Tower run, this bug is causing people to not be able to collect Crowns.
Several players reported being affected yesterday. At least one player I know who wasn't affected yesterday got the bug today.
My guild missed 10,500 because of this issue.
