Level 25 to 26 is broken

[Captain Segfault]

I get "no valid levels for 13, 11invalid looking level" when I submit a valid solution to 25.

Which is actually rather unfortunate; I still haven't figured out a good algorithm for this one, but it isn't yet big enough to exponentially crush my puny little Perl script.

right now, we only have 25 levels, sorry. i'm hard at work on more =)

it turns out that level generation is a little tricky on this problem, and is done offline and saved into a db. we should have more levels soon.

okay, there are new puzzles online now... up to about level 55 and more will be generated.

turns out it gets harder with bigger boards =)

I solved level 4 and got this:

Fatal error: Call to undefined function: board2string() in /home/.mazie/bok/hacker.org/coil/coil.php on line 94

Not good
