I don't get it.
On some other manga websites the newest chapter is usually current+1 meaning this ch197 is ch198 there...
What is even more confusing is that now the gap became +2 and the newest chapter became 199.
@happybro@shiirosagi Specifically, I think a chapter on here mentioned it quite some time ago now. I definitely don't remember the details well enough to even figure out which chapter range to look for the explanation in, but I think the main point was that the numbering is different on here from the group's own site and such because they didn't want a "missing chapter" that wasn't actually missing here, given how the site detects all that? Something like that, anyway.
