What the server log says
SCRIPT (E): @"Ford_Raptor_MonstarTruck_Data/scripts/4_World/entities/core/inherited/inventoryitem.c,1": Multiple declaration of class 'fordraptor_monster_wheel'
Fix
- Disable 4KBOSSKVehicles
Both packs ship the same vehicle scripts, so the second one stops the start with 'Multiple declaration of class'. Keep the package.
How this is known
Proven by starting a real server: 2026-10-25, DayZ 1.30.164200, smoketest (55 mods).
- Multiple declaration of class 'fordraptor_monster_wheel' (Ford_Raptor_MonstarTruck_Data/scripts/4_World/entities/core/inherited/inventoryitem.c:1)
Checked against the Workshop build of the mod from 2026-05-09. A newer build may have fixed it: DyzOps then asks to check again instead of applying the fix.
DyzOps finds this before a start (Mods → Check) and applies the fix with one button.
