So upon removing ROBLOX's Default Core Guis, I had to create a new Tool gui for selecting tools. I made the system work for selecting the tools and such, but whenever I equip the tool, it always breaks. Even ROBLOX's default ones.
This is how I equip a tool into the character.
local plr = game.Playerse.LocalPlayer
Tool.Parent = plr.Character
Again, For some reason this seems to break the tool.
