CrashMultiple reports

Palworld crashes at launch or in play after the 1.0 update

Track crashes after updating to 1.0, including the UE-Pal Exception Access Violation on PC. The most common verified cause is leftover Early Access mods, which 1.0's engine changes make incompatible until the files are fully deleted.

Memory or RAM usageMultiple reports

Palworld dedicated server RAM grows until it crashes

Track dedicated-server memory that climbs over hours and is not fully released, ending in a crash at peak player counts. Community server hosts describe the pattern consistently; Pocketpair lists server-side optimization in 1.0 but has not confirmed a specific leak.

Character and inventory missing after moving a co-op world to a dedicated server

Track co-op saves migrated to dedicated servers where the world and bases arrive but a player's character and inventory do not, reported as a player-ID (GUID) mismatch between the co-op save and the dedicated server's expected structure.
