1.12 Invalid fingerprint detected for RebornCore!

[Krutoy242]

I got this error in debug.log:

[Client thread/ERROR] [reborncore]: Invalid fingerprint detected for RebornCore!

I can't find actual errors in game related to this through.

What this error means and what malfunctions i should expect?

Error surroundings:

Sounds like the signature is wrong. Could be you have a malicious modification of the original mod. Do not use to be safe until a developer of the mod can tell you more.

malicious modification of the original mod

CurseForge distribute malicious modifications? I downloaded file from CF.

It can also just be an error on the programmers' side by supplying a wrong fingerprint.

But earlier I didn't realize this was for 1.12. This version is not supported anymore afaik, so I'm afraid you won't get much help.

On the other hand, when it is from official CF and thousands of players have downloaded and played it and it wasn't taken down by now, the files should be alright. I doubt you will notice anything during playing.
