Hi JBernal,
This issue has been reported as JIRA [UE-20612] and has been reported to occur when updating between 4.8 to 4.9 as well as 4.9 to 4.10. I have added details from your specific case to the bug report and “upped” the community interests.
However, this should not result in you not being to transition to a new map from the original. Please respond with the following logs to help diagnose the source of the issue:
- “UE4.log” Located: Engine\Saved\Logs\
- “ProjectName.log” Located: ProjectName\Saved\Logs\
Thanks,
.
