Prestige/Technology Bug. Can it be fixed?

[Zred92]

I loaded up my old saves after a while without playing and suddenly all of my old saves have hundreds of thousands of prestige and piety and are gaining thousands per month. I also noticed that all of my technology has already been researched and I have thousands of technology points. Do you know what the problem might be and how I can possibly fix it?

There was an incompatibility between versions recently (possibly when 2.4 was released - I don't recall for sure) that caused this. As far as I know, there's no fix for it but to revert to the previous version, and even that may not fix it if you've played for any length of time with the new version. I lost a burgeoning empire that way.
