So, i've been running into this problem where it states, "FML has found a non-mod file BiblioCraft-Mod-1.12.jar in your mods directory. It will now be injected into your classpath. This could severe stability issues, it should be removed if possible." this happens to every single mod. I can't get any to work. No matter what version I use either, I want to use 1.12.2 since it has the mods I want. Links to the log file, https://pastebin.com/SWqyzGyW . I looked everywhere for a solution but can't get anything. Also I'm using a multicraft host, all the servers are coming from a official source too.
