@Öffentliches Ärgernis
Now it's part of this mod: https://steamcommunity.com/sharedfiles/filedetails/?id=3523089427 .

Basically, this one should work too. If you need only this patch, you can subscribe to the mod, then find where it is, copy it to Steam\steamapps\common\RimWorld\Mods and just fix the file called About in the About folder - you need to replace <li>1.5</li> with <li>1.6</li>.
In general, I think it's a good idea to start your own personal mod, where you can store simple patches from outdated, not updated mods. Often there you just need to add a supported version (as I described above). It's very simple. I myself have an uploaded to the workshop, but hidden mod in which I store stuff (so as not to lose, it is more reliable).

Now I know where the updated mods are, but are there plans to update this one too... since this mod description made me aware of the imbalance I can't stand it :-)

logical.
