I don't know how many will remember, but during beta testing for the foundry code merge that went with Season 6, there was a feature that showed up for a while called Dialog with Object objective. Now as you can imagine, it behaved very similar to the Dialog with Contact objective, but was tied to a detail object instead of an NPC.
I and a few others were very excited to see this as it had a multitude of uses especially for puzzles. Unfortunately at the time there were bugs which necessitated it pull and the feature never made it into Season 6.
I was recently reminded of this feature while discussing puzzle building. I was hoping CrypticFrost might be willing to poke around find out what became of this and if there is any chance that it might make a return.
