Levelset "dx_abd" from the DX Boulderdash collection has 100 levels, but 80 of them is empty (as empty as a Rocks'n'Diamonds level saved with file version 1.2 can get, that is: 291 bytes).
Why not delete those empty levels and decrease the "levels" indicator to 20?
It's scary what can be found when looking... first the levelsets with incorrect levels value and now this
Btw: I think it's 14 levelsets and not 15. 15 only when counting the levelgroup itself...
Oops... This level set was automatically converted by a script -- seems that the original set had either empty levels or less levels than the conversion script expected. (I don't really know, it's too long ago... :-o )
Seems that nobody has noticed this so far. ;-)
Thanks for reporting this issue! I should fix this...
Or at least noone reported it. It wasn't so hard for me to find, either..
Seems like some new ways of investigating things is very nice... good veeery good
I think I can find more of these things... I'm afraid that the dx_abd set was just an example
