WarReaper

So, I downloaded 1.12 forge and it worked great for a while, so I decided to download it for 1.8.9. These two co-existed for a couple of weeks before the 1.12 version started crashing on start every time. So I went over to the 1.8.9 version only. Not too long after also that version had this problem. It says "It looks like you are using an unsupported modified version of the game." I will link both the crash report and the error message. The thing is, I've seen other people post about this but they never really got an answer and then the thread was locked. I would really like help with this as forge dramatically boosts my fps ingame. Here's the crash report: ---- Minecraft Crash Report ---- WARNING: coremods are present: Contact their authors BEFORE contacting forge // But it works on my machine.
