So, I'm taking over Greg-Style-Changelogs.
v1.0.3-rc2
1. You can now teleport to Antimatter Universe legitimately. Take 1 antimatter glob (which you CAN produce in Particle Accelerator BTW) and rightclick with it. If you're in Overworld, you will be teleported to Antimatter Universe, if you're in Antimatter Universe and rightclick, you will be teleported to Overworld.
2. Added Ore Enriched Pillar as Antimatter Universe WorldGen. It's a Pillar that contains ALOT of ores (it will dynamically pickup any new ores which are correctly registered in OreDict as "oreXXX", so GT and IC2 ores will definetely work), wrapped with Quartz.
3. Added various low-down tricks to Antimatter Universe. It's a really dangerous place now, get ready for... random explosions, lightning strikes, jumping like a rocket into the air, etc.
You DO WANT to fly there, because if you stand on Antimatter Stone, ALOT of explosions will happen.. like alot of them.
