Issue Summary:  
Opening an Okri’s Challenges reward results in a Server error message “Backend rejected the challenge response” with the only option being to close the game afterwards.

I have restarted the game, steam, and my PC. The problem has persisted at least 24 hours now. Any help would be appriciated, as the game is unplayable in it’s current state.

* * *

Steps to Reproduce:

1. Start game
2. Select character
3. Open the Okri’s Challenges menu
4. Select “Claim Reward” from a completed challenge.!

* * *

Reproduction Rate (Choose One):  
Constant (100%)

* * *

## Additional Information: Interestingly enough, I do not appear to be able to join games with others but can host a mission with bots. Any progress made on missions isn’t saved upon restarting game.

It sounds a lot like you’re accidentally playing on the modded realm, as opposed to the normal realm. This can be changed using the checkboxes within the launcher, above the ‘Play’ button.

Sure enough, I was on the modded realm. I must have clicked it by mistake.

Thank you for your timely response Julia. My game is working now. Consider the matter resolved.
