Project 3 - strange coloured wires


we have finished building all the required circuits in project 3, and everything seems to be running properly. however, when re-opening the file after exiting logisim, some of the wires turn blue or red whilst the others stay green.
this seems to happen randomly and with different wires each time.
after clicking ‘reset simulation’ they turn back to green and run properly.
we’ve also sent it to the bodek email and no violations were found.

this is the first time i’ve seen this sort of behaviour, is this normal? can we hand it in like this? or is there some sort of bug we need to fix?

thank you

It’s a bug in Logisim. If it works after you reset the simulation, it is fine.

thank you very much!
