Ok, so I installed ExtrabiomesXL, to start a new world. It loads, I roam around get hit with the overflow stack error for dynamite. Try it a few more times, same thing.. Lastly I went to start a new world, couldn't even get into the world cause it overflowstacked me
And basicaly just repeats that over and over
guess I should also state this happened with 1.97 and the new 1.103
