Hi All
We would like to give a brief update about the Flatland challenge and the current work in progress.
First of all, thank you all for reporting bugs and putting in requests for new features. We are working hard to squash the last bugs and prepare the launch of the next round.
Unfortunately, there were some critical bugs in the new level generators which forced us to delay the launch of the second round.
The changes that are coming in this next round are still the same as posted here.
The only Difference will be that we are updating the way the sparse_rail_generator() works. This means it will create more realistic railway infrastructures.
Given the progress in the last few days we expect to have squashed all critical bugs and fixed the level generator in the coming week.
We are constantly updating the docs to reflect all the changes in the repository, we apologize for any inconsistencies or out-of-date information in the documentation. Please feel free to support us by contribution directly to the documentation (Don’t forget about the community contribution prize that will be awarded 
).
Thank you for your patience and great contributions to this project.
Best regards,
The Flatland Team
