I am playing a pbm game as the usa - using patch 1.10c. I have got to late july 1862 with no problems but am now seeing regular fatal errors when I try to move troops or ships around. The error message is always the same whether it is a troops or ships I am moving :
TGroup.PathExists Erroneous logic, path with only one region listed
The error dumps me back to windows unless I turn error logging on - in which case I can then just continue with my orders. I can supply a pbm save turn if required.
