After redeeming the codes for 3 hand guns on GRN for GRFS I tried following the instructions that we are given for receiving these items in-game.
(To unlock the Wild Boar : 1- find the code at the "Warmongers, inc." website and enter it in the "Enter a code" box at the top of this page. 2- after you have launched GRFS at least once, come back to this page and click on the "Transfer to the game" button below this paragraph. 3- you must restart GRFS to obtain the weapon in the game. For instance)
It seems no matter how I try to "Transfer" the items to GRFS they never show up after restarting the game. I am hopeful that this is just a bug and not some big issue that might keep me from getting these unlocks so if anyone has any idea why it's not working I would appreciate an explaination.
