Won't be back at my real computer for a while. However, I did add something else from the RP that wasn't in the MM before that I may have messed up. (Or was it from @Endocore 's enhancements?) There are two spatial scripts... One at each ladder now. It was supposed to unlock a dialog line with Marcus about the tunnels. You could talk to him about the tunnels if you hadn't found the bodies yet. I can't check the variables on these until I make it back. @Darek , could you look at this, if you haven't already done so? If you already looked at it, then I have no other ideas, as I haven't added anything else. Edit: I am reading this from my phone. Missed it before. Looks like you already mentioned the variables for entering the tunnels. I don't know what could be going on then.
