SilverBullet,,,, i was trying to launch a domination solo game and got this error message,,, i get it when i try any map now, but i ran a couple games yesterday or the day before. not sure what changed.

You're loading save games @SilverBullet1234 ?

Save game compatibility was broken extremely recently. Saving on versions @ 2.0.18746 or later should work.

DanVanAtta commented 4 years ago

To some extent we don't expect players who play only releases to ever see this issue as we would increment the version number. In theory we already on a 3.0, but given that all 2.0.x's have been non-compatible development versions so far, we have by convention have not been incrementing the major version number.

If the game major version number were 3.0 then the error message would probably be clean.

There is argument to clean up this error message regardless (and probably still allow for bug report submission as could be a legitimate problem)

no, i dont really play "domination" so i have no saved games, i just wanted to test it out and launch it.
