That is somewhat annoying if the limit is hard-coded... 180X94 is "OK"-- I did, really, want a much larger map (hence the doubling) but it might suffice if I can produce one that big 
Edit:
Found Something :
Code:
<Row Name="MAX_SUPPORTED_MAP_X">
<Value>152</Value>
</Row>
<Row Name="MAX_SUPPORTED_MAP_Y">
<Value>96</Value>
</Row>
I am going to test it now with higher values, see if it updates it 
Well, editing them speeds up the issue, it seems-- removing them, on the other hand, causes things to just freeze up completely, but maybe that it is just taking a VERY long time to generate...
