As you know, I personally hate the "Disgusted" moodlet's current icon of a furiously grimacing face. I want to move that to "Appalled" and replace "Disgusted"'s thumbnail with the one for the chew motive for dogs (the tipped-over trash can) - which I find to be both more appropriate for a reaction to a plate of spoiled food or a pile of trash, and less of an eyesore. So, I switched the thumbnail filenames in the Buffs.xml file.

But, when I tested it by firing up testingcheatsenabled and zeroing out the hygiene of one Sim to get the other Sim to get this moodlet, the moodlet's icon is blank.. Is this because of some way the moodlet icons are loaded?

Did neither one of them show up? What exactly did you change in the Buffs.xml?

I did not test the Appalled moodlet.

Here's my change:

<BuffList>
<Hex>Disgusted</Hex>
<BuffName>Disgusted</BuffName>
<BuffDescription>DisgustedDescription</BuffDescription>
<ThumbFilename>w_knock_over_garbage_can</ThumbFilename>
<AxisEffected>Uncomfortable</AxisEffected>
<EffectValue>-5</EffectValue>
<TimeoutLength>10</TimeoutLength>
<FacialIdle>FacialDisgust</FacialIdle>
<ShowBallon>False</ShowBallon>
<NeededTraitForRobot>SentienceChip, HumanEmotionChip, CleanerChip</NeededTraitForRobot>
</BuffList>

I also replaced the balloon for the Disgusted moodlet similarly.

I noticed that the buffs that use that thumbnail have an entry: <SKU>EP5</SKU>
Maybe you need to include that.

Thanks, I added the EP5 SKU tag and the knocked-over trash can icon showed up.

I didn't need to add anything to the Appalled moodlet because it already used a base-game icon even though it was a Late Night moodlet.

So it's working? Cool.
