4.13.1 Hotfix; can no longer place characters

Did you check through the AI and Behavior Tree listings on the 4.13 released thread to see if the changes you are seeing have been listed?

We do highly recommend remaining on one build for active development unless it is necessary to update for specific features or fixes. Updating does contain an inherent risk of potential breaks as code changes or updates can have negative effects on a project.

If you have specific information that I can follow to recreate this on my end I’ll be more than happy to attempt to reproduce this error.
