Roll back to previous version in Steam?

[ex_]

I have steam based install - can I/how do I/ roll back to before 1.05 came out?

I am in the middle of a big, complicated mission, and this update just changed the game entirely. I need to finish this first!

Thanks

Hi ex_, if you right click KSP in the Steam client then click Properties, you'll see a Betas tab.

In there you can select the last stable version, it may still be 0.90.0 however.

thank you! I saw someone mention in the 1.05 release thread that they rolled back to 1.04, so hopefully that is possible. Will go try...

EDIT: It did work, and brought me back to 1.04 within minutes!

Note, you will have to edit your persistent and maybe quicksave to say "1.04" at the top of the file, if you had previously loaded it inside 1.05.

It may load up initially with no ships in flight - DON'T PANICK. Just go to the load game menu and find your quicksave and load it.

follow-up question.

If I did this roll back, and not actually saving a copy of my KSP folder prior to updating to 1.05, am I indeed reverted back to the old heating mechanics, or am I possibly getting the new mechanics?

I was on my way to sending a very large ship to Eve landing/return for my first time ever. I do not really know what aerobraking at Eve was like prior to this new update, so I can't say for sure whether the new heating or the old heating is present.

Do you think I could possibly be playing some type of hybrid install because of the way I rolled back? Again, I did not have an opportunity to decline the update. Kind of peeved about that. Sucks to have fast internet - but also, there did not appear to be a way to cancel the download install on Steam. that's really crappy. I could very well have ruined weeks of planning for this particular mission

And that's why you should not play the Steam copy through Steam but from a separate folder. You could delete the physics.cfg and try to verify the integrity of the game cache in Steam to get the 1.0.4 one. Don't try to run the game before because 1.0.4 will otherwise create a corrupted version. Another option would be to go to the first post of the Linux thread in the unmodded forum and get the 1.0.4 physics.cfg from there separately.

thanks. that's helpful info. I'll try it.
