1.70.2

Bug Fixes

  • Fixed a crash on startup, and when pressing Apply in the Mods window, caused
    by mods whose gameoptions.txt leaves a blank line where a text settings
    default value belongs.
  • Fixed a crash on startup for anyone with extracted main.dat files in their
    Defcon folder whose names differ only in capitalisation from the originals.
  • A missing font file no longer closes the game, Defcon falls back to another
    font instead.
  • Fixed a crash when connecting to a game in rare cases.
  • Fixed a crash caused by the unit placement window and sidepanel.
  • Screenshots with HDR enabled using the DirectX11 renderer on Windows now correctly
    captures the HDR output instead of the SDR output.
  • Transitioning from fullscreen to windowed with a resolution change now grants
    that resolution instead of giving you maximized windowed.
  • The MacOS green zoom button that makes the game fullscreen now writes that to
    preferences, previously this was out of sync and would not persist after a
    game restart.


Graphics Changes

  • Defcon now has a graceful fallback if your desired renderer fails, it will
    try other available renderers and tell you if you had a failure and if it
    succesfully recovered.


Modding Changes

  • A mod whose gameoptions.txt does not match Defcons format is now refused, with a message naming the mod and listing exactly which settings are missing or unrecognised.
  • A mod whose travel nodes leave part of the sea unreachable is refused the same way, and the message explains why.
  • Both checks now run whenever mods are applied, including the mods restored when Defcon starts.
  • A mod that is temporarily unavailable, on a drive that was not ready for instance, is no longer dropped from your saved mod list.
  • Mods missing from disk are marked as not installed as soon as Defcon starts, rather than only after you open the Mods window.
