I have yet to encounter any Aberration dinos on Extinction with this mod enabled, although I hear from others that it does work.

oh ok i have this mod on my extinction server and i can not see any aberation dinos spawning across the map

I just tried it on our server and it doesnt seem anything is spawning there. I think it has to do with the fact that the spawn locations seem to be biome specific, judging by the 'where they spawn' info in the decription, and Im going to guess the new map has different biomes.

Edit: In looking at the comments, it seems obvious now. The Dev Kit for Extinction still hasn't been released, so the biome region names aren't available yet.

oh ok so when the biome info gets released then maybe the mod will be updated

I also removed it b/c it was not working for creatures, but other stuff did work

since the dev kit has come out for extiction will we have progress for this mod to work on the new map. As having the aberation dinos would be cool :)

Anyone tried it and knows for sure the Creatures are spawning?

yeh i have this running on a extiction server and only thing which seems to spawn is the aberation ovis
This is is due to there already being a ovis spawn on extiction
