OK, without all the names that might be confusing…
The bottom right corner of the board is SZ42.
Directly above that is SZ43
Next in along the bottom is SZ41, the SZ containing New Zealand
Above and East of that is SZ44 (south of Hawaii)
Solomon Islands are in SZ45
The south-eastern Aussie SZ (bottom edge of board) is SZ40
Northeastern Aussie SZ (south of New Guinea) is 46
I think that covers all of the errors with ABattlemap in the Pacific
Around South Africa,
the one west of South Africa (that adjoins Angola) is SZ27
the one east of South Africa (that adjoins Madagascar) is SZ28
The only other error that I know of in the main, unpatched, version of ABattlemap is:
If you have units in SZ9 (Ecan, Nova Scotia area), your unit summary lists those units as being in SZ5 Baltic for some reason.
