"released healthy prisoner" mood buff not stacking

[Nerdygamer1]

Releasing a healthy prisoner gives a +2 mood boost, but only once, regardless of if you release more or not. I was going to change that, but in the Thoughts_Memory_Misc.xml file, the <defName>ReleasedHealthyPrisoner</defName> has a <stackLimit>5</stackLimit>. If I'm understanding correctly, that means that releasing a healthy prisoner is supposed to stack up to five times. I ran a quick test world with no mods and released three healthy prisoners. The first one gave a +2 mood boost, but the other two didn't boost the mood any further.

What am I missing here?

<stackLimitForSameOtherPawn>1</stackLimitForSameOtherPawn>

Not sure what the intent of that value is, might restrict the buff to 1 stack per faction released or something. I imagine raising that to 5 will make it work like you want in the situations you want though.

Yep, that worked. I saw that line, but, since the mood boost is generated immediately upon releasing the prisoner instead of when they leave the map, I assumed it was in place to prevent you from releasing a prisoner, recapturing them, and then releasing them over and over for an easy mood boost farm. That, coupled with the fact that I was so stuck in my preconceived notion that I was going to be adding a <stackLimit> meant that I didn't even consider changing that.
If you look in the Thoughts_Memory_Social.xml file, you see that insults are capped at ten with the <stackLimitForSameOtherPawn>. So, I should have researched more.
