This is a severe bottleneck for ambitious mods. The LL_FourPlay plugin allows this limit to be patched via a simple edit to the LL_FourPlay.ini file. By adding a line like uMaxArraySize=512 , modders can expand the array size, allowing for more settlements, quests, inventory items, and other game systems to be managed simultaneously without errors.
