Hello I'm new to using multisim and I'm trying to recreate this circuit for christmas lights. It does blink as intended but it crashes after 5 seconds or so. I tried using https://forums.ni.com/t5/Multisim-and-Ultiboard/Christmas-Lights-Circuit-using-4060BT/td-p/2362202 to troubleshoot and check if I missed anything but I couldn't figure it out. Can anyone help a bit please or offer any ideas? Thank you.
