Not using a Nether with this team.
I was having this issue earlier but I didn’t really think it was a bug.
My Agor Apocalypse I wish I got a screen shot before I bred him, but he was always getting gross amounts of EXP. I always figured it was because he was from a god core thing or something.
When he catches up with the rest of my party, I’ll post a new screenshot.
I am still getting this bug in .0.5.2. My nether is still getting double the xp of any other creature in my party.
