Happening in Creative Mode, 2.0 Devices. I haven’t checked 1.0 Devices. But you can no longer name/rename Timer Device. They appear with a blank name and referenced as “unknown device”. Naming is critical with event binding so I hope this can get fixed soon.
How to recreate: Just put down a Timer Device in Creative Mode (may need to be on 2.0 devices). Try to rename from either the top menu or from the gear menu - the option doesn’t exist.
