Is anyone else having this issue? Every once in a while (happened 3 times now) when I go to the Nether, there is a creeper waiting inside the nether right at my portal who proceeds to blow up right when I enter. The first time it killed me, and subsequent times I've been able to jetpack away just enough to barely survive with one heart, but it turns off my portal. I'm worried about getting stuck in the nether one of these days if I don't happen to have flint and steel with my when I enter. I was always under the impression that overworld mobs don't spawn in the nether and can't travel through portals. Is this normal now to Minecraft and I just missed it? Or is this possibly an addition to one of the mods? I've tried lighting up the area around both my overworld nether portal and the nether nether portal. Nothing has worked so far. Any suggestions? Thanks. BTW, I'm running the latest version of Mindcrack pack.
