I'm stuck on case three (Diggin' in the dirt) I don't know if this is a glitch but here's my problem: I'm stuck where I need to ask the arcaeologist a question which leads me to finding out about his trailer. It just wont let me ask the question which is something along the lines of "Did you write the report on the site?" or something like that. I went on a walktrough to check that I hadn't missed anything and I haven't I've also processed all the evidence and had the spiel where I look at the tape which shows me the picture of the archaeologist showing that he authorised the report. I cannot find anything I've missed and the rest of the evidence in in the trailer that I can't get to. Is this a glitch or have I really missed something huge??
