Spawnrate issues on mobs and ores

Hi, I'm finding real difficulty finding any mobs other than Aerwhales and Zephyrs and maybe the occasional swet but I have yet to see a single Moa/Phyg/Aechor plant as well as a complete lack of Gravitite ore. I've dug out the bottoms of entire floating continents and have yet to find a single one. If anyone could link me to an Inventory editor compatible with Aethermod blocks etc. (so I can actually get some ore) I would greatly appreciate the help.

not sure about finding it, but SPC and TMI are compatible

Thanks, I can actually get the gravity set bonus now.

More "glitches" though.

• Aerwhales constantly spinning around and colliding with blocks, ALL of them, even the ones not stuck.

• I fell into the regular world not far from my original Aether spawn and for some reason I decended in a completely different spot to find a new portal not placed by myself that links to a portal in the Aether also not placed by myself

the Aerwhales thing is a known issue
and the Aether works kinda like the nether so leaving it at a different point from original can cause that to happen

Spawn rates are messed.
