The biggest problem for long-time players has been the bug with certain NPCs vanishing off the map and never returning. I'm truly sorry this was a bug in earlier versions and this bug remained in savegame files. This update features a substantial hack applied to saved games when they are loaded that tries to fix the incorrect flags and counters that some NPCs have carried forward from earlier versions. This should result in these NPCs reappearing in many locations at new intervals that have also been adjusted in their scheduling counters.
The next update will likely restore the movement and dynamic pathfinding of the NPCs and also introduce their former competition with the player for tablets and other treasures hidden in Hyperborea. These things were commented out but some of the old code has already been incorporated to give the NPCs agendas and schedules of their own.
The following update after that will be in tandem with the release of the manual for the game.
