I still haven’t found any reliable workaround for that. It would be nice to have any feedback from the dev team if this is going to be fixed in the upcoming hotfixes.
If there is any reason why the editor utility actors can’t tick in 4.23, then it could even become an opt-in feature, disabled by default, e.g. by a checkbox in blueprint class settings. (“CanTickInEditor” or something similar). But the deprecated Placed Editor Utility Base didn’t cause any trouble with that.
