Well the worst occurred and I had to do a fresh re-install of SH5. I reloaded the mods on the list and went through the Canal and it went pretty good (In fact it was a fine job you did- it was almost accurate). So, perhaps you can hold out for awhile and assume it's OK until I reach Bremen. I'm in the Total Germany campaign on the first patrol. Sorry about the screenies. I thought my screen taking software could take in-game pics but it seems only the desktop.
Again great job on the Canal!
