I am making a BungeeCord server. There are two modded servers that have over 100 mods, I need sponge for plugins. SpongeForge does not support either of these versions of forge and the mods are unstable with any other version. forge-1.12.2-184.108.40.20665-universal and forge-1.12.2-220.127.116.1159-universal . If there is any solution or any way I could run SpongeForge on either of those to versions please tell me. Thanks!
So one thing to note (I havent had time to look up your exact versions) is that sometimes having slightly different Forge number will still work.
If there is a version of Sponge that has a Forge version that is similar to your (but not exact), you might want to make a backup, and try that one.
Have you actually tried running SpongeForge in that environment? The build of Forge listed in SF is the minimum version needed to make it work; you should be OK using more recent versions of Forge, provided massive changes have not taken place. Give it a try and see.
