ive removed betterfoliage for now until a fix come's out

Got the same problem, it started after updating to forge 2768 (also happens on 2767 but not before I think) here's my crashlog if needed.
EDIT: Just noticed this is a duplicate of #206

Getting same issue. The mode does not work with newer versions of forge. downgrading to 2760 seems to fix. Need something changed in the mod for newer versions of forge.

Getting the same issue as well with Forge 2768.
Apparently NotEnoughIDs had the issue, maybe look into it (NEI's author solved the issue).

I'm having the same issue and I'm on Forge 2769. I tried it with just Better Foliage on, and it still crashes immediately.

Crash report:
crash-2018-10-13_21.37.02-client.txt

It seems there are actually four different issues about this open; #206, #207, #208, and this one.

Yeah, it's not just NEID. I don't use the mod, just BetterFoliage.

NEID author has fixed the issue.
Still hoping Better Foliage's author can get around it too, I love Better Foliage.

Same crash on start up. Made sure and isolated it by adding a mod in a at a time, came to BF, crashed. Just removed all mods from the folder but BF and, same crash. Using Fo9rge 1.12.2-14.23.5.2768
crash-2018-10-14_19.53.31-client.txt

Figured it would be easier to just add to this issue since it's the same thing instead of opening a duplicate.

nah its just the stack overflow error...

I have the same problem and reported it to forge. Here are some more crashreports: MinecraftForge/MinecraftForge#5194

@TimGoll if you've got this exact problem, this is not a Forge issue.
Forge updated some things in its newer versions and most mods concerned have followed thru and updated, Better Foliage just hasn't done so yet.

Yes, you're right. At first I thought it was a forge error, because there was no modnamd in the stacktrace.
I only linked my issue to thid one because I've found multiple reports online and maybe they are helpful to the dev to fix this bug

@the-realest-stu, why don't you open a PR?

Actual even if Better Foliage builded from sources. Confirmed.

I'm not opening a pull request because it's a bug.

Confirmed, the-realest-stu's commit fixes the issue. He contacted me about it, and I asked him to hold off on releasing it to avoid confusion, as I plan to make a release myself soon.
Official fix is incoming.

You could try building the mod from the-realest-stu's fork which fixes the issue. I did so and it works perfectly with the latest versions of Forge.

Fixed in 2.2.0
