I was on 1.14.3 and had a couple mods also made for 1.14.3 and then one day Minecraft decided to update to 1.14.4 without telling me and now I have to wait for the mod creators to update their mods. Is there a way to stop this from happening before 1.15 comes out and I have to again wait weeks to use my mods? All the answers I could find on this were outdated.
go into your launcher and there should be a tab call "Installations" from there select the profile or make a new one that you want to have the modded installation to be on. then change the version of that installation to "release 1.14.3-Forge[Forge Version]. Next time you load into that installation it should be back to your modded version
