Recently, I lost the ability to access some challenges, even some that I completed, that were on the far right.

Is this a bug or is there a restructuring going on?

Same thing happened to me. I don't really have time to complete the new challenges that have showed up. Oh well

Agreed. I've tried to at least keep up with the easy ones that have popped up, and the didactic ones are self-descriptive: leading you on to the next until you can't stop

occasionally we'll modify the graph such that you need to do a challenge to get to where you were before. i just changed it again because i didn't like how i had it, so you're probably clear now.

Yeah, I can access them again. Thanks

...Where have all the challenges gone, long time passing...
Solved some challege offline (smellassweet) and found, that i cannot access it now.
- Must be some change in the challenge tree.
Well if i may say so, find that kind of annoying. Couldn't new challenges be arranged in new branches, so there would be no need to speed solve?

It would be nice if, if you have ever been able to see a challenge, then you will always be able to see that challenge, regardless of changes to the tree. Maybe that's hard to implement though.
