I know it's too much work for every side quest, but I'd really liked that afetr solved one main quest, the character involded in might have an added sentence As "I didn't expect that from him" or "remember what we talked about" or "Don't disturb. Back later" instead this damnt "Well", "what?" "Geralt?"
What Marcin meant by saying it's not a "bug", is that it's not a simple issue of improperly implemented dialogue that we could fix with hotfix patch (some people suggested that). It's not the case of us having the recorded dialogue we could use there, being blocked by some bug.
It also does not mean that we don't consider this as an issue.
