Just sounding an early alarm about the new system. When the Party Loot System is enabled for an instance, the system currently negates autoloot ID settings. Places like OGHN/H uses exact autoloot ID lists to disallow unwanted and certain heavy items from clogging party inventory, especially equipment items that are both heavy AND unstackable.
To attempt electing out of this system, I tried nolootid, noshare, autoloot 0 but it did not work.
I also found each monster in OGHN, with a 1-man party, to be dropping normal loot at a seemingly high rate to which each monster was dropping all its item table per kill. My inventory was full of equipment and I was at 120+ Coagulated Spells not even past the bottom right room on phase 1 in OGHN. One example was killing a clump of Dead Body Maggots produced 5 or 7? Coagulated Spells upon kill. Something appeared off about this.
I tried FOGH-N and although drops were still flowing in my inventory against my will, the drop rate appeared normal.
Anyway, please take a closer look at the system, suggest pulling this patch back and testing one normal playthrough and item loot system before reimplementation.
