How to install a previous mod's version? (Downgrade mod)

[Dragony]

Hi!

Today one mod got an unfancy upgrade, but with a critical bug inside. Unfortunately I can't play my huge save without that mod. Since I don't know if the mod gets fixed, it might be neccessary for me to undo the upgrade, i.e. downgrade the mod. If that is not possible then my huge save (and my trust in doing mod upgrades when they become available) would be lost.

Any help is greatly appreciated. Thank you!

You can go to the mod portal and download the specific version there.

I.E.: https://mods.factorio.com/mod/pyrawores/downloads

I guess you can manually download an older version from the mod portal here: https://mods.factorio.com/

Then you will need to put that older version inside the mod folder of your Factorio (and remove the newer one I suppose),
the actual path of the mod folder depends on your operating system.

You shouldn’t need to remove the other. The mod manager will allow you to select which version to use. Even though the newer one is bugged and you'll probably never use it, I believe keeping it will prevent the game from saying there’s an update available until an actual update/fixed version is released.

Right solution: write to mod author and explain why the mod works wrong. Wait until next version.
