Hi @taramakage, CHALLENGES were not included in this distribution, where will they be included?

Additionally, these challenges (mainly C2) are caused by a malicious contract attack (packets loop).
It's like giving rewards for fixing reported bugs.

They are a part of tasks completion pool

They are a part of tasks award

thanks for the clarification
