SephirothSpawn's Tilemap Bug?

[Kain Nobel]

Hello and good day! I don't really need help with coding or anything (not yet at least o.o) I'm more here to just ask a basic question.

Anyways, what was the common complaint about SephirothSpawn's Tilemap re-write? Was it a game-crashing bug or a case of things not being displayed properly or what? I'm just curious because I might use it or at least take a swing at fixing the bug. Besides that, his extra autotiles script requires the Tilemap re-write which I hope to be implementing into my project soon.

Also, I have his 4.0 test bed, dated as 2007-07-31, he's never posted one beyond that date has he?

Thanks ahead of time for any info you might have.
