Logged in twice today (each time into Player House) without seeing any Server Boost Icons or Notifications. No icons come up during the whole play session, zone changes etc. do not help, only a relog brought them up.
This happens quite frequently, sometimes I only figured while playing, from xp numbers, that a boost must be up (and relogged accordingly). However, that the notifications/icons don’t show up reliably on first Login is bad, I am sure I missed out on some boosts already.
