Instructions to revert Master of Orion to the previous version

[Bertiux]

Greetings explorers,

As you know, the latest update of Master of Orion, v51.2, brought some big modifications in the pollution and gravity mechanics. After this patch was deployed, the old savegames were loadable, however the conditions of certain planets got heavily modified, affecting your ongoing games.

In order to let you continue your old games in the previous conditions, we have enabled the build v49.5 (Official Launch) in an alternative Steam branch. Here is how you get to it:

1. Launch the Steam software, but do not run Master of Orion
2. Go to the Games / Library tab
3. Right click on Master of Orion
4. Select Properties
5. Go to “betas” tab
6. Select the build that you wish to play in the drop down menu (no password required)
7. Close the window
8. Let the game update

To go back to the latest version of Master of Orion, simply select the "NONE" option from the drop down menu.

Pro tip: If you continued and old game after v51.2 and overwrote your savegame, please note that you can go back to the desired turn by going to “Path to Victory” / “View Timeline Graph” and clicking in the point of the timeline that you wish to restore.

Please note that this version does not allow mods, as it's the build prior to the mod support implementation.

Conquer the Stars!

I take it that this only affects old saved games, and that new games will continue to adhere solely to the rules of the v51.2 patch?

Actually, I was able to finish my old saved games anyway, since the pollution overload problem self-corrected after a few turns. For me, the most troublesome thing right now is the ludicrous behavior of the AI races constructing essentially nothing but vast numbers of colony ships. Any progress towards fixing that?

Awesome. Going to give this a try. Can't get past turn 100 without the game hanging on the new version.

Edit: Semi-awesome. The only options I have are "Opt Out of All Betas" and "Official Launch" - but assuming that version works I'm good.

Edit 2: Rolled back, got to turn 225 with my usual settings, without any problems. Note I am talking about new games here. I have not been attempting to use previous saves.

Thanks for offering this!

Thank you for making this option available to us

Thank you for doing this, and letting us know how to revert. It is good to see that developers care about the fan experience.

Thanks for sharing this.

Reverting to the previous version now.

Nevertheless, given that you recently announced new DLC races and features, we cannot stay on an old version branch forever.
The problems with the new pollution mechanics go much deeper than "the old savegames no longer work". The system by itself is flawled in its current state, even on fresh newly created games.
It makes the game tedious, frustrating, and a micromanagement hell in the mid-late game (again, I'm talking about fresh v51 games, not old savegames).

Please, consider this before releasing more MoO builds...

You can always use the "no pollution" mod that is in the workshop. I hate the newer pollution mechanic so much that I just use that. Sadly it also makes the AI enemies better than usual too, since they dont accidentally ruin their own planets and kill themselves from overpollution (I saw an AI take a terran down to toxic and starve to death with the new pollution system...always a bad sign for a mechanic when even the computer cant use it right).

This is also how to play your saved games that date pre-Antares as of Dec. 1. I keep seeing people asking about it in the forums, and figured reminding people on a sticky thread might be useful.

This did not help me. I lost 16 hours of game time for my save game. Done for awhile. Discouraged.
