That is correct, the topic was started by that user and yes I am looking inside of all topics not messages.
Its quite strange. If I load up /latest?assigned=me&solved=yes I can see the topic in that list I just for some reason cannot get it any other way.
Additionally if I search for just plain old: assigned:jordan_hms in:solved I only see 6 responses but 3 of them are invalid (not assigned to me). I have well over 300 topics currently marked solved and assigned to me.
