Decided to try the
del *.bin in
\maps first as this seemed the most logical common root. (& even the slowdowns/script issue I saw could be a direct result of map data corruption.)
So far everythings working now without issues. I wonder how the map data was corrupted but at least I know how to solve it now!
All ToW players owe you a debt of gratitude for keeping these games running!
