My main problem is that the simulator and my breadboard are showing different behavior when connecting the Transistor (BC547).

I am specifically referencing the section titled "Oscillator Core". The exact circuit I am trying to build can be found at this link. NOTE: I built all simulated diagrams with Falstad Circuit Simulator. BC547 Connected - Re-connected the BC547 Transistor and started seeing inconsistencies.BC547 Removed - Removed the BC547 Transistor to confirm all other components are working.Intended Circuit Diagram - The complete circuit I am trying to build.I will try to explain my problem referencing the following pictures:

I am trying to build an oscillator circuit that will output a Triangle Wave and Square Wave in tandem (trying to dip my toe into building modular synthesizers). I am brand new to building circuits, so I apologize if I use the incorrect terminology.
