Mosaic Controllers and January 1st, 2020


ETC has identified a bug within Mosaic Designer that could cause controllers that are either reset or uploaded  specifically on January 1st, 2020 to watchdog

Description/Explanation of Issue

To be clear, this bug is only an issue on Jan 1, 2020 and no other day.  Any date Jan 2 forward will be fine.

If a showfile is uploaded to any controller or a controller is reset running any version of Mosaic software (Version 1 or Version 2) on January 1st, 2020 and the project contains the following items; An Astronomical and/or a lunar trigger and has “Execute Time Triggers on startup” set, the controller will watchdog.

Please note any controller that is not uploaded to or reset during the exact January 1st, 2020 date will continue to work without issue.


ETC does not recommend uploading or resetting your Mosaic if your show meets the above mentioned criteria.  If it is critical that a config be loaded on Jan 1, 2020, it would be possible to adjust the date of the controller, upload the config and then adjust the date back to Jan 1.  If at all possible, please wait until Jan 2.
