As the title states, when I try to load C&B the launcher crashes with a severe error message stating that it is from the mod itself. Im not sure how to go about getting this resolved.

For any bug reports please provide the following,

• MC Version: 1.12
• C&B Version: 1.12
• Do You have Optifine: no

I have a similar problem but when I tried updating to the newest recommended version of forge it didn't fix it what would you need to see to try to identify the problem

You'll need to give me some of those messages, or screenshots, or logs. I need something to work with.

"The game crashed whilst there was a severe problem during mod loading that has caused the game to fail
Error: net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Chisels & Bits (chiselsandbits)"

This is all I can give you. I can't seem to be able to access the crash logs

That just says that an exception was thrown, and doesn't tell me what the exception was. Unfortunately this is like stating that the sky is blue, gives us the knowledge that something happened, but not remotely what.

if your launcher isn't giving you access to other logs perhaps trying a different launcher would help. I usually use vanilla launcher, and I don't have any issues starting the game, or getting the crash logs.

I am using the Vanilla launcher, its strange that I'm not able to launch the game or access the logs.

The logs folders should be available in the same folder that contains mods folder, should be marked as logs or something else. I can't imagine why you wouldn't be able to access them.

I was looking at a completely different location. Here is the last log I have
2017-08-04-1.log.gz

That file only contains,
[12:42:10] [main/INFO]: Setting user: linksys1221
[12:42:15] [main/INFO]: LWJGL Version: 2.9.4

maybe clear them out, then re-run the launcher. and upload all the files? Or look though the logs for the error before uploading them.

I was having the same problem with the mod where it would crash whilst trying to load the game. I found where it showed a loading error, but I don't understand any of it. Maybe you could have a look at it.

@Insanimous You've removed the part of the log with versions, but because net/minecraftforge/registries/IForgeRegistryEntry is missing, I assume your using a old alpha/beta version of forge for 1.12.

C&B Requires at least the first recommended version, most of the logic related to registration was re-written for that release.

Thanks, it fixed it. I had installed an older version of Forge before for it to be compatible with Optifine, but I deleted Optifine and got the recommended Forge version and it runs fine now. Thank you!

@thecakeslayer Any news on this on your end? Is your problem the same?

I had issues launching with optifine installed so I just needed to reinstall forge. I should have done this first before coming here. Whoops.

So I suppose that means no more issues? All clear?
