I don't know if it the right place to post my problem but I do it anyway :
My problem is not new, first when I launched for the first time this Modpack (the 2nd of July) I had already problems due to JEI,
Then today its an other thing, I checked my crash logs and it seems coming from MooFluids, it says ;
The mod moofluids is expecting signature @FINGERPRINT@ for source MooFluids-1.12.2-1.8.12.02a.jar, however there is no signature matching that description
And after; No fingerprint found!
I think it's the only issue crashing my game when entering my world, I give you however the whole crash report, its the last crash report, I tried relaunch my Launcher which is Twitch and my computer a few times, but no solutions, 2hours ago I was playing without any problems :
Thanks for you help, regards.
