Several third party SmartApps are having this issue. I’ve submitted a bug report #232741 - it would help get some visibility if others would submit support tickets as well.

It looks like the execution of Routines/Phrases is failing for many community SmartApps including SharpTools, SmartTiles, CoRE, Routine Director, etc.
Looking into the logs when the failure occurs, the following error message is shown under the filter for the ROUTINE that was attempted to be executed:
10:09:24 AM: error groovy.lang.MissingMethodException: No signature of method: script1234567890987654321.execute() is applicable for argument types: (null, null, null) values: [null, null, null]
Possible solutions: execute(), autoExecute()
