the file has a broken resistor figured out how it happened i picked up the resistor and moved it without placing it back down then hit the back tool to undo stuff which resolts a ghost object and in doing so destroys any project after opening if u save resistor that is broken causing save issues @Mike Bushell i hope this helps u for steam

When expressing circuit diagrams, it is common to fold multiple individual wires into a single, thicker "wire". See for example: https://eater.net/schematics/6502.png, examining the various address and data buses. When building actual circuits in CRUMB, it would be nice for cleanliness purposes to use some metaphor for a ribbon cable: a single thicker wire which could be routed to and fro throughout the circuit, but finally opened up at either end to expose its numbered or coloured ends, to be connected to ICs.

Hola me serviria mucho que agregaran mas circuitos integrados como el 7447 en un video de youtube vi que en anteriores versiones si estaban disponibles el 7447 y el 7448 ahora ya no, tambien que antes habian baterias como fuente de poder ahora ya no, si pudieran agregar eso me serviria muchisimo
