, please look into the penguin, angler, and deepwater spawner that the (Plesio is mapped to); when they are remapped with a copied version of those spawners they never stop spawning dinos, i had 80k angler fish and 20k penguins on the map, i had to remove the mapping of those spawners and just remap the NPCs.
As for the current build i will be testing here in 10min
