Raid Bases avoids land players use. It refuses chunks where players have spent more than `site.max-inhabited-minutes` (15 by default), spots within `site.player-distance` of a player, and any spot with a chest, furnace, bee nest, sign or other block entity, a named or tamed mob, an item frame, armor stand, minecart or boat in the fort's area. See [Where forts rise](https://mbcz.mintlify.site/raidbases/where-forts-rise.md). Before the first block changes, the whole area is saved to disk. When the raid ends, it is put back and checked block for block. ### What happens if the server crashes mid-raid? On the next start, Raid Bases restores the land from the journal, saves the world, then deletes the journal. A normal stop puts every fort back at once before the plugin shuts down. ### Can players keep blocks from the fort? No. Nothing broken inside a fort's area drops, not even ores from the ground under it. Everything there comes back when the fort goes. ### Can players hide loot in a fort? No. Chests and other block entities can't be placed inside a fort's area. They would vanish with their contents when the land is put back. ## Raids ### Why didn't a raid rise? Check these in order: 1. **Players online:** scheduled raids skip a turn when fewer than `schedule.min-players` are online (2 by default). 2. **Room:** the server already has `max-active` raids standing (always 1 in Lite). 3. **Schedule:** `schedule.enabled` is `true`, and the tier has a weight above `0` under `schedule.tiers`. 4. **World:** `worlds` names a loaded world. 5. **Land:** the console logs `found no land after 24 tries (last: …)`. On worlds with lots of water, raise `site.attempts` or allow some `site.max-wet-columns`. `/raid list` shows the time to the next scheduled raid. ### Do more players crack the vault faster? No. Progress fills one second per second while anyone is in range. Bring friends to fight the guards and to stop rivals from taking the vault. ### What if nobody cracks the vault? When the tier's `time-limit-minutes` runs out, chat says the fort held out and it collapses with no loot. ### Can I use TNT on a fort? Yes. TNT that goes off inside a fort's area breaks fort blocks, ignores PRO wall HP and drops nothing. A blast from outside the area can't touch the fort, and nothing breaks the vault. ### Do guards burn in daylight? No. Guards also take no fall, suffocation, drowning, magma block or fire block damage, and they can't hurt each other. Fire Aspect and Flame still burn them. ### Why is the vault a lodestone? On Paper 1.20.6 the vault block is behind an experimental flag, so Raid Bases uses a lodestone there unless the world has that flag on. It works the same way. ### Will the first raid after a restart lag? The first raid after a restart can cost a short hitch while Java loads the raid code and the guards' mobs. Later raids don't. ## Custom forts (PRO) ### Do I need WorldEdit installed? Only to build and save your fort. Raid Bases reads the `.schem` file itself, so the raid server doesn't need WorldEdit. ### My schematic fort says it can't be found. Keep the file name lowercase. Tier layouts and commands are read in lowercase, so `schem:MyCastle` looks for `mycastle.schem`. Check the file is in `plugins/RaidBases/forts/`. ### Do chests in my schematic keep their items? No. Containers rise empty on purpose: the vault is the loot. Sign text, banner patterns and player-head skins do come across. See [Custom forts](https://mbcz.mintlify.site/raidbases/custom-forts.md). ## Licence and editions ### Why does PRO disable itself on startup? It has no valid licence key, or the licence server couldn't be reached and the key hasn't passed a check in the last 72 hours. The console says why. Claim a key with `/claim RAIDBASES` in the Discord, paste it into `license_key` and restart. See [Installation](https://mbcz.mintlify.site/raidbases/installation.md#claim-your-pro-licence). While PRO is disabled, `/raid` gives Bukkit's internal error line. ### Does PRO need internet? Yes, for the licence check on startup. If the licence server can't be reached, PRO still starts when the same key passed a check in the last 72 hours. ### Can I switch from Lite to PRO without losing my config? Yes. Both use the same files. Swap the jar, add your key and restart. ### Can I run Lite and PRO together? No. Install one edition only. ## Server software ### Does it run on Spigot or Folia? No. Raid Bases supports Paper `1.20.6` through `26.3`. ### Which Java version? Java 21 or newer. Paper 26.x servers need Java 25. ### Can I use Bukkit `/reload`? No. Use `/raid reload` for config and messages, or a full restart. > [card] [Discord support](https://discord.gg/kgHNjJsB2t) > > Questions, licence keys and support.
