Hello Riders,
The ICARUS team would like to inform you that we are already aware of the Sealed Nebula the Chaos issue description as "Cannot be extracted. Soul crystal is destroyed when removed". This is a known issue, the sealed fellow can be extracted without destroying any crystal and more. We will make sure to make the localization for the Sealed Nebula the Chaos right. Apologize for the inconvenience.
Again, you can extract the Sealed Nebula the Chaos without destroying any crystals.
- ICARUS Team.
