You can fix this by making OR gates with tri states buffers by connecting each input to both inputs of a tri-states buffer and connecting the output of each tri-state buffer in the output.
It will only output the same output as when a pin is disconnected or 1. So, it won't repeatedly flash, because the flash is caused by the interaction between signal 1 and signal (Connected and 0)
I have the same problem as you so I think it has to do with our machines, but I don't know for sure.
I think it's not intentional, but at least you will be able to use the sim until Sebestian fixes the bug .
