Sometimes, all networks start being saved many times in one second, or in small amout of time. At least is what appears on console https://hastebin.com/ezovasigax.md

fluxnetworks-1.12.2-3.0.16-11.jar
forge 14.23.4.2705
sonarcore-1.12.2-5.0.15-13.jar

I cant update to sonarcore-1.12.2-5.0.15-15.jar to se if the problem is fixed there because there is no download button for that (the one that exists, downloads the 1.12.2-5.0.15-13 version)

Fixed: Couldn't recreate this issue in the upcoming version, if it reoccurs please open a new issue with new console log.
