What version of MacOS do you use? I use High Sierra with 3 external displays, and my windows are almost always in different places when I unplug, plug back in. All monitors are the same model (this might make a difference), but I always plug them into the same port they were connected to previously. One hypothesis I have is the order I unplug / plug in the monitors matters. Edit: after some quick testing, I can't seem to reproduce any issues while just briefly leaving my monitors unplugged. The issue I notice the most is that windows get put back on the wrong monitor. e.g. window A from monitor 1 is now on monitor 2 and window B from monitor 2 is now on monitor 1.
