The balancing out is a thing that i understand but i won't expect, Ian had more in this update, but that's the same in every update. Before Lena was leading in that department, so i think it's natural that in some updates we might get more of Ian and others more of Lena.
However, in pure CG, seems like people didn't find or didn't count some as content:
So what i found is the next scenes which involved other characters for both Ian and Lena
I might forgot or missed some scene.
So yes.. she has less SEX in this update, one scene less so people wanted another... that's for sure. And her "relationship" are more physical, only having strong emotions involved with Ian (if you chose so) at the moment.
So i personally don't count this update as lacking in Lena's content, she had this problem from updates before that her partners are flawed in some way or another; so it's hard to get a good relationship option besides Ian.
However, this might be intentional, because the game is still growing, so it might have to thinner the paths (Being with Ian (+Holly maybe) or not) to open others kinds of paths and kinks later i dont know.
