For those who have an error partaining to gas masks because of Vanilla Expanded apparels, go to your rimworld workshop folder. Which would be 294100, and then Portraits would be 2937991425. Click on that folder, and then click on "Mods" folder. Then go to VEApparel. Opening that would have 2 other folders called "Defs" and "Textures". Open textures and find "InnerHeadgear" the gas masks will be there. Then open "Defs" with either notepad or notepad++ or any other code editing software, and search for this line

<PortraitsOfTheRim.PortraitElementDef>
<defName>PR_InnerHeadgear_VEApparel-an-gasmask</defName>
<portraitLayer>PR_InnerHeadgear</portraitLayer>
<graphicData>
<texPath>InnerHeadgear/VEApparel-an-gasmask</texPath>
</graphicData>
<requirements>
<ageRange>13~999</ageRange>
<apparels>
<li>VEApparel-an-gasmask</li>

and

<PortraitsOfTheRim.PortraitElementDef>
<defName>PR_InnerHeadgear_VEApparel-cn-gasmask</defName>
<portraitLayer>PR_InnerHeadgear</portraitLayer>
<graphicData>
<texPath>InnerHeadgear/VEApparel-cn-gasmask</texPath>
</graphicData>
<requirements>
<ageRange>13~999</ageRange>
<apparels>
<li>VEApparel-cn-gasmask</li>

Or alternatively you can just search "VEApparel-an-gasmask" and "VEApparel-cn-gasmask" using Ctrl+f and then delete the line of code above. This will prevent the mod from using the gasmask texture and thus wont give everyone the gas mask. It is a temporary remedy CHEERS!
