IT conflicts with every api I have installed on the modpack. It is a custom modpack with over 200 mods and very much stable with just this little hickup with gendustry and tesseracts directly touching eachother.

here is my crash log.

It doesn't conflict with anything and has nothing to do with your crash

Your pressure pipes versions is very out of date - http://bdew.net/pressure/

Try updating it first and if you are still having problems paste the new crash

Due to no response I'm assuming that this is fixed and closing the issue. If the problem still exists please comment here or open a new issue.
