Non existant error message

[Aqua_Turneur (Aqua)]

i am completely lost…

so i am currently trying to make the Game Of Life by Conway on roblox but an issue appeared so to fix it i had to create a table of the precedent frame, wich i did but then i realised that the table of the last generation and the table for the current state are syncronised somehow so i searched up on documentation and foudn this function to clone a table containing tables :

but when i tested the game to see if it worked i had 0 fps for 10 seconds and then the script just stopped working, so i looked in the ouput but i only found this :

there’s the details about an error message but no actual error message wich is really confusing me

here’s my script :

-- variables

local mainFrame = script.Parent
local controlsFrame = mainFrame.ControlsFrame
local grid = mainFrame.Grid
local generating = false
local running = false
local template = grid.Template:Clone()
local previousPixels = {}
local pixels = {}

-- settings

local gridSize = 50
local aliveColor = Color3.fromRGB(44, 174, 255)

local aliveChancePercentage = 10
local aliveAmountRange = {2, 3}
local aliveAmountToReproduce = 3
local tickSpeed = 10

thank you so much for any help

By default, studio will only keep the 5,000 most recent error messages. Anything beyond that is deleted. Try adding a task.wait() in the deepCopy function and running it for only a moment.

I figured it out : the problem was that every element in the table was refering to another element so the table would loop through it self
