A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.
The scorpion stronghold Hidden Moon Dojo says: Look at all face-down cards in a target player's provinces. If you destroy a province this turn, its owner will not refill provinces during his next Action Phase.
does that mean that after the player buys there provinces, that they will not refill that turn?

Not sure which person you mean by "the player": the one owning the Stronghold, or an opponent whose Province was destroyed.
In any case, "Action Phase" is not the same as "turn." Provinces can still be refilled in all other phases (Dynasty Phase, Events Phase, etc.).
