Most towns are actually 199x199. x100 to x300, for example of one side of a town, is 199. 100 -> 200 is 100 blocks walked. 201 (start of next 100) -> 300 is 99. Which explains why people can't center their portals. And other problems... Like being unable to have two blocks as a center rather than one. /rages at self I literally spent an hour trying to figure out why I didn't have a two-block center... now I did. xD Ugh
yep and this means that all the towns that I have made posts for are actually 199x199 instead of 200x200.
