We interrupt your daily flight to bring you a quick and small hotfix. Thanks to Rusty CLWK for reporting this major bug.

Here is a full list of patch notes:

Fixes:

• Fixed an error where certain actions in Chapter 2 could cause the boss to not spawn and prevent progression.
  • If anyone was affected by this change, it can be bypassed by modifying the game's save file. Send an email to lmg3864games@gmail.com for further instructions.
