I was less prolific and only solved Disconnect four, Tents and Trees, From Start to Finish and Star Battle (422). It was great fun, but I need to practice speed solving and time management.

The puzzle has been retracted and will return once it has been fixed. Thanks for bringing it our attention.

I'll pull it back until the implementation mistakes have been corrected.

All genres use the same applet and as far as we can tell it is implausible (although with some bugs you can never be 100% sure) that only specific genres would give these problems, with the exception of when I recently broke Fillomino.

As far as Bram's explanation does not suffice, I would sooner suspect a more random factor to be at play, not tied to specific genres.
