Minor update

● Stack size for logs, redwood, blackwood, etc. increased from 200 to 500.

● Copper coils can now be scrapped into scrap brass.

● Added corpse despawn parameter = 0, meaning corpses will never disappear.

Note: We are focusing our efforts on developing the "Merchant System", along with adding a bicycle system, hundreds of new loot items, a wide variety of furniture, various advanced new walls, and cool vehicle parts. As a result, some player feature requests or minor non-urgent bugs may be delayed. Thank you for your understanding!
