me and a friend were playing on my single player world with the mods listed above installed. My friend tried to build a "nether door", and got portal blocks. he placed them, and realizing that you can not place portal blocks side by side, tried to break them. This somehow teleported him into the portal, but while it was loading, his game froze, so he quit the game. Seconds later, my screen also froze, and crashed. Now, when I try to open my world, it loads, then freezes, sometimes showing my T-rex, and it crashes with the following message: "An unexpected issue has occurred and the game has crashed. We're sorry for the inconvenience." i would really like to play my world again, as I spent a very long time creating it. I should also probably note that I am using a MacBook.

*EDIT*

I really need help..

now it says "it looks like you are using an unsupported modified version of the game.

when i hit more details, it says "The game crashed whilst unexpected error
Error: java.lang.ArrayIndexOutOfBoundsException: 8249"

i have no idea what that means.

wait... what?! I retried it and it says an issue has occurred and the game has crashed were sorry again!

Try taking out the world out of the saves file. Reinstall minecraft. Reinstall the mods and try playing the world again. You game might have gotten corrupted.

when I attempted to open the world after reinstalling minecraft and the mods, it still crashed, with the note

The game crashed whilst unexpected error
Error: java.lang.ArrayIndexOutOfBoundsException: 8249"

ok i did that, but when i tried to open my world it still crashed. however it said

"The game crashed whilst unexpected error
Error: java.lang.ArrayIndexOutOfBoundsException: 8249"

what the?

heres the crash report
