The Central Loot Economy (CLE) appears to be restricted to spawning items of the same type in bulk, disregarding the values set in the 'RespawnTypes' and 'RespawnLimit' parameters in the Globals.xml file. Adjusting these parameters from, for example, 12 to 50, does not have any effect on the loot spawning behavior.
Upon enabling the lootspawn, lootcleanup, and lootrespawn logging settings in the cfgeconomycore file, it appears that the economy is restricted to spawning a maximum of 10 items of the same type every 30 seconds.
This implies that the respawn parameters in the globals.xml file are not functioning as intended. If these values are increased, the economy should be able to adequately restock despawned items.
