If you don’t have Sponge installed, this isn’t the place to be looking for support - it’s not related to Sponge, and you’re more likely to find help with Forge or the developers of the mod you believe is causing the issue. It’s not in Sponge’s jurisdiction to fix, so don’t ask us.
Oh, and when you do ask Forge/whatever mod for help, for heaven’s sake include a
fml.latest. Logs save lives.
Both Forge and Sponge are generally forward-compatible, so new minor versions shouldn’t cause an issue. If a version of Forge doesn’t work with the latest Sponge, that’s when you should be posting here and asking for help.
Straight from the Forge Rules and EAQ Thread:
- DO NOT ask for help with any version besides the latest MC version.
Given that you’re on 1.12, that would be the latest MC version. Regardless, you should always test things on the latest version of Forge (and whatever else you have), just in case.
If you run a server with Sponge[Forge], your server will have access to the Sponge API and be able to run any plugins that use it. Unlike (some) mods, plugins do not need to be installed by the player and are handled server-side. It really depends on what your situation is as to whether Sponge is worth it to you, but there are a couple really good plugins that I prefer over anything Forge, Bukkit, or Spigot has. Besides, I’ve always found the community here to fabulous ^^
