Description:
crash on launch.
idk whats causing it. just saw something about dynamic surroundings so I figured id paste it here
didn't have this issue until I updated to latest version.

You have two DS core JARs. Go into your mods/1.12.2 folder and delete the DS JAR there. Then try starting again.

That didn't work. I sitll get a crash. Here's the report.
