quando tu scrivi il skript, tu usi il ChatGPT?
^^^ ^^^
I barely know italian it's my fourth language

The first reason I believe this is AI generated:
1. ChatGPT is stupid, and can't code right in any syntax, especially a niche and unknown one such as skript
- You kind of forgot which skript addon you were using, and changed it from the invalid expression 'format gui slot 1 of player with' to 'set slot 2 of player's chest to'... How do you get it wrong twice

2. Your robot buddy kind of forgot to cancel clicking in the gui (Not even a rookie would make that mistake)

3. What is this:
set {_playerMoney} to balance of player
set {_missingMoney} to {_cost} - {_playerMoney}
Any human would not set a boilerplate variable that they use ONCE, when they can just plug in the original variable (Only ChatGPT would do this)

4. ...
close chest with player
Are you teaching the player how to close a chest nicely? The hell is this...

All in all,
1- Human devs
0- Ai devs

Stop using chatGPT

Im not sure what this is, but its all kinds of wrong.
12 errors.
Reading the code, it screams AI (ChatGPT) generated.
Its awful. Most of it just invalid code.
