Solved Issues with player.inventory.GiveItem

Hi, I encountered a strange glitch with the GiveItem function, whenever I give a player an item, their inventory will spawn all the items as usual, but when you pick up any other items or spawn one into your inventory through the F1 menu it doesn't appear in the inventory until you somehow get the server to update your inventory. Things like taking off clothes or putting them on, changing the active item on your belt or placing a wall and other things like that will update the inventory, but without doing that, picked up items won't show up in the inventory. Has anyone else encountered this? If so how did you work around it?

EDIT: Nevermind, the issue was unrelated to that function.
