I've tried installing the 6.4x configs for this mod pack, namely Tellion's and it has worked perfectly. The only issue is that when the new gas giants are looked at at an angle, they stop rendering and become invisible. It's not game-breaking, but very annoying, and if anyone knows why it happens, that would be great. I've already tried re-installs and I've checked through the config files to see if there was a fault there, but I couldn't find anything weird. Help would be appreciated, thanks.
