I'll skip the when and why of the matter, but I've been disabling the GTAO DLCs with dlclist.xml and extraupdatecontent.meta and everything has been working fine. Most of the weapons from the DLCs that were available in SP's Ammunation are gone. But the Knuckle Dusters, Machete, Machine Pistol, Proximity Mines, as well as the Ill-Gotten Gains tints are still "partially available."
Their slots still exist in the Ammunation store menu. They can be hovered over and "purchased." Cash is subtracted from the protagonist, the "PURCHASED" image pops up, but obviously no tint is applied or weapon is added to the inventory because the item does not exist/was not loaded into the game.
I'm not sure why these select weapons still appear though. Their respective DLCs are disabled, and even if I am to delete the DLC files this issue still persists. I can only assume that unlike the other DLCs and their weapons, there are files outside the dlc.rpf that are allowing them to still appear in Ammunation. I just can't find them. Any ideas?
