I seem to have stumbled upon another serious bug.
Returned to Midway in late November 1944. Was awarded an upgrade to the Tench class boat.
Accepted and set up loadout, crew etc for next patrol.
Cannot start next patrol. Whether I choose to start outside or inside of harbor, game crashes to desktop during loading.
Rebooted machine & restarted game a couple times, no change. Likewise, fullscreen vs. windowed mode.
If I go back to a save before returning to Midway & refuse the upgrade, I am able to start next patrol in the old Balao. But what fun is that?
As before, using only FOTRS:UE 1.24 + 1.26 patch.
