Good Afternoon fellow gamers, Me and my brother were playing Minecraft Java Edition (version 1.7.10). I had created a modpack for my brother since he loves modded Minecraft, it was working for several days, sometimes crashing but that was expected.[/p]
But, a few hours ago. We were in the Twilight Forest Dimension (great mod). We were just walking around, it crashed. Which was pretty normal with such large mods in a relatively mediocre gaming PC, I launched Minecraft, it started loading. Then crashes after a few seconds loading.[/p]
I will post the crash log below![/p]
Here's the crash log.[/p]

Pneumatic Craft is crashing, maybe try removing that? Seems to be quite a few people are experiencing it, you could also try a different version, but, I believe development for 1.7.10 for this mod has stopped so you can't really do much else.

Grimallq has a perfect paste.ee for you to read before you post in the Modified Client Support:Read This
Delete pneumaticcraft's config file and let it rebuild on the next launch.
ahn yes thank you fellow gamers
