Just thought I’d share this info with you all.
Found where the spawn restrictions on Titanosaur are applied.
Applied to NPCZoneManagerBlueprint_Land_18 on theisland within PersistentGameplaySublevel_DinoSpawns. Min and Max number of spawners is set to 3.
NPCZoneVolume_29 then covers the whole island, and is set to count wild and tamed dinos. Hence the 3 server limit.
Just in case someone want to break their server.
