Lucanis romance bug after Act 1 decision
Because it's DEFINITELY a bug that lucanis is perma-locked out of romance if you don't save Treviso, while you get to still romance neve eventually for the EQUAL and opposite decision? Especially while not telling us so, with text simply saying that growing the relationship will progress slower after being hardened (the SAME thing it says for neve's romance, which is still possible while lucanis' isn't as far as anyone has been able to discover)
EA wouldn't punish one of the romance options that would be predominantly chosen by women while most male players get to save a city AND get the girl. As well as having a romance that completely locks you out of the best ending if you pursue it, when NO OTHER companion romance is tethered to a big plot decision like that.
