This Hotfix solves the following behavior: In some rare circumstances, depending on timing, when M580 CPU detects that BMENOC03xx disappeared (for example: in case of hot swap of BMENOC), M580 CPU may go in a managed ‘Exception Stop” condition, and STOP executing project. Please refer to the Readme for detailed information. This hotfix can be installed on Unity Pro V11.1 S, L and XL packages.
