When i open my technic pack when i try to load a world the screen gos to the saving chunks
and loading world and then those sets of words start quickly changing back and forth. What
does this mean? I believe it has something to do with java does anyone have experience
with this?

Don't get it because it's work in progress and you can wait for a stable version which has
more!

Don't get a snapshot unless it's deffinetly stable and you don't care about the
consequences.
