Re: [PC] Can't Trigger Companion Romances [Potential Spoilers]
@Morokip Have you been travelling around with Bull and Dorian together? That's necessary to start their romance off (at some point you then have to speak to them at Skyhold). Blackwall and Josie, even if it happens, is easy to miss, since it's just a few comments in banter and overheard in Skyhold, at some point you can speak to them about it. Sera, Varric or Cole are probably good people to take with Blackwall to hear comments about his crush on Josie. It may be too late if you've already done Blackwall's personal quest.
I've used the banter trigger thing on CE before and had the romance between Bull and Dorian trigger (not sure if I used it for the Blackwall/Josie one), so that shouldn't be an issue. I just ran around the Hissing Wastes (good place for banter) triggering banter for quite a while to make it happen.
Mods shouldn't be an issue either, unless you're using any which alter the dialogue trees of the characters involved.
If you have flirted too much with any of the characters involved, or been in a relationship with any of them, the romances won't trigger.
