# GriefPrevention3D v17.5.0
**Wiki:** https://github.com/castledking/GriefPrevention3D/wiki
## Highlights
- **Fixed negative claim block balance on `/expandclaim`** - Expanding a claim no longer silently bypasses the block-sufficiency check when the player's name lookup returns an unexpected value, which could leave players with a negative block balance.
## Bug Fix
The block-sufficiency guard in `resizeClaimWithChecks` compared `player.getName()` against `claim.getOwnerName()`. `getOwnerName()` resolves the owner's name through an offline player lookup, which can return `"Unknown"` or a cached display name that does not exactly match the online player's `getName()`. When the comparison failed, the entire block check was skipped and the resize was allowed to proceed regardless of available blocks — leaving the player with a negative balance after the fact.
The check now compares `player.getUniqueId()` against `claim.ownerID` directly, which is reliable regardless of name resolution state.
## Migration
No data migration or configuration changes required. Players who ended up with a negative balance will need an admin to restore their blocks via `/givepet` or `/setblocks`.
