A server side fabric mod that lets the player harvest and reuse vaults and trial spawners.
Features
Vaults (both normal and ominous) and trial spawners are harvestable with iron level or higher pickaxes with silk touch.
Vaults have a 1-hour cooldown per player after opening and a 1-hour cooldown for all players when placed.
Player placed trial spawners properly spawn ominous loot when ominous.
Player placed trial spawners are empty, and I have left it up to the mod user to decide how they want to fill them (remember that spawn eggs fill spawners).
