I cannot remember off the top of my head where this particular demo ends, but that sounds about where this one does? I'm currently working on getting another build out but don't have an eta on it.
However, that build will have a quest tracker in it so problems like this should hopefully not happen.
Please just give me some more time. Games are very much a side thing for me but I'm doing my best. The game has a lot finished but just still needs more time in the oven.
