The issue was indeed with one of the mods I had (GoProne), and not forge itself. Thanks for the help!

My issue is that Forge keeps crashing upon attempting to run Minecraft due to failures to parse version spec. It runs for a half-second before closing and reporting a crash. The Forge version (33.0.7) is apparently experiencing a syntax error, the offending statement being "[33)". I had searched for anything related to version spec parsing failures, and the only instance I had found was in the Mod Development section of the forums, being this post in particular. This further supported my theory of it being a typo of some sort in Forge, I am just unsure of where. I followed the directory to the class file mentioned in the first line of the stack trace, but that was only a script to call the error, not being the offending instance. The stack trace is as follows: [main/FATAL] [net.minecraftforge.forgespi.language.MavenVersionAdapter/]: Failed to parse version spec [33)
