Hello, I recently tried launching Forge with a lot of mods because I got really bored. I got all the right mod versions I wanted and made sure everything would work. Once I started it up, everything was loading nicely and then it just suddenly crashed. The reason was as the title implies "no more entity indicies left." Could someone please explain what that means because I have only a rough understanding. If anyone could help me be able to run all of these mods that would be great. (If some mods have to be removed I will do that) Thanks in advance. I'll leave the pastebin link here ---> https://pastebin.com/W2rjsfhm

thanks for your help

Whenever i would use mods in general like forge or technic, (in this case only forge) I hit play in minecraft for my forge installation and it starts up onto the screen before the minecraft home screen loading in all the mods and right before it finishes it crashes whenever it would be finishing. I appreciate the help here is the crash report: https://pastebin.com/6FTY5dqa
