Is it intentional that this would allow a new player to join, look at the last dice results, and Sow the Seeds to match, before immediately Harvesting?

It’s a friendly catchup mechanism, but can also be exploited by a team if it’s guaranteed that for each player you persuade to unidle (or in the case of dynasty-inactive players, start playing), you can immediately trade X resources from them.

It wasn’t intentional per se, but did I notice that after submitting and not bother to add more wording to prevent it.

for that, then: too advantageous to recruitment in the late game, and too advantageous to new/inactive players in the early game, which we are still in. If the next round had some rare-ish rolls, a new or inactive player could coast past the majority of active players to get a good haul of whatever Resources they liked.

Unfortunately for those reasons

Was noted on Discord that a Harvest action “that would have involved nothing” can still be performed as a null wiki edit that’s rolled into another editor or just adds empty space, so this CfJ may be redundant.

(The fact that the null Harvest action had been performed would be recognised by “The historical fact of the occurrence of a defined game action is itself considered to be gamestate, tracked in the history of whatever resource is used to track the gamestate modified by that action, where possible, or in the wiki page Gamestate Modifications if this is not possible.”)
