i don't know specifically because i don't even know half the mods i have, but i know for a fact that the animals mod isn't working because none of the spawners are showing up in the inventory.
One should also note that now all hints of a modlist has disappeared completely from the current running instance of tekkit, and all instances i've tried starting afterwards, except for the item subsets bar at the top of the inventory screen. This was after the...third time the technic launcher has updated today. Changing the render distance doesn't really seem to change anything...nope, wait, now even more of my items have disappeared. Now the big sidebar on the right that lists all the items only has 38 pages.
On a side note, when i said everything was fog, i meant none of the textures had loaded for anything. Even on the smallest render distance i can still see the ground for several feet in front of me. The only thing that was visible THEN was when i tried hitting a tree i could see the cracking animation, but it was clear too.
