Coordinates bugged on some older maps

[Dovvah]

For example on Eastern Kingdoms 5.4.7.18019 shows 85_83 tile for middle of EK

Same thing happens for Kalimdor, 8.1.5.28938

Doesn't happen for every map of the same build number; coordinates are fine on Azeroth 4.0.1.11927 but bugged on Kalimdor 4.0.1.11927

Indeed. Nice catch! Will hopefully have some time to look at this before Shadowlands hits. If not, it might be a while.

Applied a temporary fix for this in 1e80c41, it now shows a message instead of faulty coordinates. Will have to add coordinate support for these maps at some point down the road, so leaving this open for then.

Dunno if this is related and you probably already know but the ADT grid is wrong on these unsupported maps which is potentially the cause.

It seems like it's the exact same offset for every map, exactly one ADT up and to the left
