Plugin version 1.2.4, managed scripts were usable in build promotion processes (with Promoted Builds plugin version 2.28). After upgrading to version 1.3, the promotion process hangs and is unresponsive when trying to use managed scripts; if the script content is copied to the promotion directly, then the promotion succeeds. Seeing this with both command shell scripts and powershell scripts. Only way to clear the hung promotion out of the build executor is via jenkins restart. Also causing high CPU usage by jenkins/java.

On the same build job, both command shell scripts and powershell scripts work during the normal build process (inside of "build steps").
