You are, most likely, manually allocating/deallocating memory

you store pointers to polymorphic classes

Upp::Vector<DiscordModule*> AllModules;

which do not have a virtual destructor, in a container

class SmartBotUpp{
	private: 
		Upp::Vector<DiscordModule*> AllModules;
		Discord bot;
		
		Upp::String name="";
		Upp::String token="";
		
		void Event(ValueMap payload);
		Discord* getBotPtr();
	public:
...
};

SmartBotUpp::~SmartBotUpp(){
AllModules.Clear();
}

AFAIK, you can click on memory leaks in TheIDE, and it will show you where this memory was allocated. I can be wrong, I haven't seen memory leaks in my code for very very long time Rolling Eyes

One interesting thing about U++ is that you almost never need to call new/delete or malloc/free.
