QoL Improvements:

  • Adjusted the way late-game upgrades are hidden when they are far out of reach (locked behind much further waves or ranks than you can achieve).

  • Added an info box to the Mimic Spawn Chance text in the Astral Boss Map Perks (because some players might not have the Mimic unlocked yet by the time they play the Astral map, and so don't understand what this boss is).

  • Added text explaining common issues and fixes for players having trouble creating or signing in to a cloud account.

  • Cleaned up the FAQ menu.

Bug Fixes:

  • Fixed bug where you could join the PvP Immortal Boss event on the wrong day.

  • Fixed bug where offline progress time did not count towards automation upgrade timers if you were below wave 2000.

  • Fixed a few rare issues related to the Cloud Save failing.

  • Fixed various typos, UI issues, and other minor bugs.
