If you're a Cyberpunk 2077 player who completed the Spellbound mission and paid 30k eddies for a double reward, but only received 11k instead, you're not alone. The wiki suggests that the mission's money reward has not been updated to the 2.0 economy. Don't worry, though, as there are several possible solutions to this issue.
The first solution is to contact the mission giver and report the issue. The mission giver may not be aware of the problem, and by reporting it, they can take action to fix it. It's essential to have a save file handy, so the mission giver can check the progress of the mission.
Another solution is to check the game's settings to see if there is an option to enable the double reward feature. The game settings may have an option to enable or disable the double reward feature, and it could be disabled by mistake. Check the game's settings and enable the double reward feature if it is available.
If you prefer to wait for a patch, you can do so. The developers may be aware of the issue and are working on a fix. Keep an eye on the game's official website or social media pages for updates on any patches that may be released.
Lastly, if you've tried all the above solutions and still can't get the double reward, contact CD Projekt Red's support team. They can help you with any issues you're facing in the game. Visit the support page on the game's official website and submit a ticket with the details of the issue. The support team will investigate the issue and provide a solution.
In conclusion, these are the possible solutions to the issue you faced in the Spellbound mission in Cyberpunk 2077. Try contacting the mission giver, checking the game's settings, waiting for a patch, or contacting CD Projekt Red's support team.
