We have a couple of important events programmed to trigger on Card date a number of days after Date/time of change and a number of minutes after Closure date.
We have been advised that this may fail so we “safeguard” by triggering again after an extra interval or two, like this:

Still, in some cases none of these happen, and the event never triggers.
Is this a known problem, and are there any more robust workarounds than just adding a lot of extra intervals?
