On Experimental 1.19 version of DayZ (Livonia, not confirmed on Chernarus) - Zombie inventories from randompresets are duplicated multiple times, filling the entire zombies inventory with loot. This only occurs on zombies, cargo presets for clothing/other containers are working correctly.
This is confirmed to only be happening on DayZ 1.19. using the stable branch of 1.18 with the exact same mission files causing the cargo presets to spawn correctly.
