If anything, the presence of a cap on total land is a bug. [url=http://forums.cybernations.net/index.php?showtopic=98598]When it was first hit a couple of years ago, at 50k, it was requested to be removed and admin said he did[/url]. But clearly it was only raised and it hasn't been removed/raised further yet [url=http://forums.cybernations.net/index.php?/topic/114306-remove-land-cap/]after being requested[/url].
Regardless of that, your 'bug report' doesn't make sense. Having much of something doesn't make it infinite, nor does it make you invincible. And why didn't you report Hime's tech level while you were at it, if anything it makes him much harder to destroy than Timmehhh's land does(no need to answer that btw, I know why).
