Where did you download forge from? How exactly did you install it? What launcher are you using? Please provide as many details about what you have done as possible to help narrow it down.

Except, Optifine doesn't work with forge on 1.15.2 right now, regardless of what mod you use. Once it is brought up to forge compatability, I imagine it won't matter which biomes mod you use.

1.12 is no longer supported on these forums due to age. Please update to a modern version to receive support here. More information on supported versions can be found in the LTS link at the top of every page.

Yeah, I've used the twitch launcher and had varying results. Running through the vanilla launcher seems pretty easy, -download the twitch modpack -make sure you have the same version of forge installed normally as the twitch pack needs -Create a new MC installation with that forge version, and just point the game directory to the pack folder in the twitch instance folder -profit!

@OliviaaaIn the future, on the page you download Optifine from, there's a link to the Changelog for each version. If you look in the changelog before you download, it will tell you which version of forge it needs, or if it is not compatible with forge.

Yeah general consensus is that the twitch launcher sucks bad and breaks stuff with forge all the time. I forget who it was that has something in their signature for how to run twitch mod packs using the vanilla launcher and not the twitch one. You could probably google "how do i run a twitch modpack with vanilla launcher?" and get something telling you how.

Please share the exact steps you used to setup your workspace

Look at the change log on the optifine downloads page for the version of it you are downloading, and it will tell you which version, if any, of forge it is compatible with

Your debug.log should start with something like:

Make sure you post the full debug.log, that looks like it might only be part of it.

Nope, not unless you pay them, pretty sure that's ended.

Why doesn't Microsoft support Windows 95 anymore?

Show your launcher installation settings screen, and the contents of the mods folder please

It also explicitly states 1.12 is no longer supported, likely singled out for mention because it was the go-to version for a long time while the 1.13 rewrite happened.

It is possible that no one that has seen your post knows. Try reinstalling everything again? Don't install 32 bit java at all? Delete graphics drivers completely and reinstall? Those are probably my best guesses.

You're not using Java 8

I am not sure what you are asking. Please provide more details, be exact what you are trying to do, and what you have tried. Code and logs are preferable

I would search the forums for CapabilityFluidHandler and then jump in and give it a try. If it doesn't work, post code/logs and someone will likely help

a lot of those changes are still used in 1.15, that's why I linked it.

Here's another link with some changes since the big rewrite, I think they still apply. Hope it helps! https://gist.github.com/williewillus/353c872bcf1a6ace9921189f6100d09a

Forge blockstates have been removed: https://gist.github.com/williewillus/30d7e3f775fe93c503bddf054ef3f93e

Unplug game controller/USB device

It's still doable, just not supported on these forums. Like running Windows XP, you could do it, but if you have any issues, Microsoft won't help you, they'll tell you to update to a modern version. TLDR; latest version and previous version are supported here, anything earlier than that moderators will lock threads/delete posts, as there are too many old versions to support here.
