ok guys i'd need some help here. being lurking around forum for quite some time now. i follow the installation guide line the same with my friend, then we generate the drug and it did infact work and spawn MR. GJ's gun but problem is only I can use it even though me and my friend both have those files installed and followed the same instruction.
for example, spawn a GJ's legendary, if i pick it up and use it it's fine, if my friend picks it up, it'll immediately turn into a green/white rarity crappy gun. some custom GJ's gun or sleep master's molded gun he is able to use, but 99% doesn't work on his computer.
another thing is, if he was to generate the drug directly in willow tree to create item, it'll work and he can use the drug but still can't pick up the guns. but if I was the one to drop drug for him to pick up, he'll see only cyan color of the dropped item and not see item picture itself what is dropped.
one last thing after i realize. after i inject drug, the weapon drop rate become very small. what i mean is, when you kill an enemy, they only drop health pack and money but not guns where as previously they will almost always drop a gun especially the crimson soldier.
