Hey, so I've had many issues with my modpack I put together.

Apparently, if I type in "tank", or "end" among many other things, (I find new problems every once in a while), it shows an error with "Fatal error" and takes me back to the multiplayer screen. And since NEI keeps what you last searched for, I can't play the game unless if I go to my saves and delete the NEI folder is what I found out.

Also, when I open up the openblocks starter book, that also causes the same error. Another thing is with buildcraft fluid pipes.

Every once in a while I seem to find another fatal error like these.

After doing some research, I have found out it was the new forge fluid system.

I've tried downgrading versions, but that doesn't seem to help. Not too sure if I'm using the wrong version, or what.

Does anyone know the correct version I should use? Or is there another way to fix all these problems?

It didn't come with a crash report, for some odd reason, so I can't help you there.

My modpack is 1.7.10, by the way.

Thanks in advance for your help.

I really appreciate it.

Alright, I'll give that a try. Thanks!
