Toys Repeatable (NADORC) has always been flaky for me. Sometimes it will be a few days after my cooldown ends before it's up at a reasonable hour (i.e. not 5am).

All the other missions I pay attention to are about the same too.

The only thing I notice is rarer is Inspect Civilian Freighter, but I'd still believe it's RNG and not a change in the game.
