Not sure if you are even looking for bug reports since it's still in development, but I've realized that there's a bug with lovers. In some occasions (in my case almost always), if you select a pawn that has a lover, the lover pawn gets correctly colored pink. But additionally also all other pawns to the right to that pawn in the colonist bar also get colored in pink.

Here's a screenshot to show what I mean, you see that there are also pawns colored that are not lovers of the selected pawn: https://i.imgur.com/cVbhsd1.jpg
