put 8 spicy ribs in cabinet, press E to tonauac, and he died :(
is this mod has some incompatibility with other mods?
for example, my cabinet has 40 slots due to enhanced storage. also installed FU.

So i just mimic'd your situation (enhanced storage and FU) and I was able to get the buffs just fine. Is there any other mods you are using that may effect either food or storage

Improved food description.
Think thats all i have for storage or food mod.

Maybe... its not compatible with mod races. maybe.

hrm, nah mod races shouldn't be an issue either. Tonauac exploded because it couldn't read something in the container, or something returned in a funky way. ill take a look at food description, but I doubt thats the case

uh, so im back home, try one more time with 9 hotpot, worked this time.
so my answer is, kluex doesn't accept some food. lol.
still don't know why.

oh no, i think i know the reason.
im testing tonauac's fate with various food.
pasty, hotpot, apex fritter and others work like charm.
spicy rib, meat stew, shepherd's pie will make him explode.

if you install FU, FU add new mechanism to foods, the 'carnivorefood'. for meat-type food.
'Improved food description' mod shows me that new effect has added to those foods.
thats why this mod doesn't work for me when trying to put meat.
i think this can happen to any user that use FU.

long story short, it has incompatibility with FU's modified food.
kluex must be vegetarian.

Except I downloaded FU myself to test this out and all the food you are describing works for me just fine. So it cannot just be an FU problem.

My guess it's coming from improved food description. I'll have to check it out

So I used the exact same food you did, with FU and Improved Food Descriptions, and it still went through just fine. So it must be some sort of mod that is sneaking in some changes and messing some things up. I really have no idea how to fix this because I can't recreate the issue you are experiencing:X

well, then i need to try again hundred times to know which mod is messing me.
Anyway, thanks for help.

Just remember to test it with newly created food rather than food in your inventory. That could also be a very important factor when debugging like this.
(since food is unique in that modded data can persist in the item itself even though you uninstalled the mod)

Well Tounauac suicided after some modded food was added and guess what? She gave me eternal lightness.

Well until I mech'd.
