I keep hearing that but I can't reproduce it. I can get Wyll to say he's sorry that I didn't choose him but if I F8 and ask him he says something like he doesn't feel the connection and has a tankard to keep him company.
Poor Wyll is bugged even worse than Gale. I haven't been able to trigger his party scene and I've only heard of one person in the wide world of the internet who managed it - but they had no idea how.
Even the easiest to romance -- Astarian suddenly developed standards and Lae'zel told me I had displeased her too often.
I've had Astarion turn me down, but only if I asked instead of waiting for him to ask me (or if I said I'd think about it). Lae'zel
always offers and I've no idea why. She hates pretty much everything I do. These triggers are very confusing - maybe it can all be blamed on Early Access, but I dunno.
