I have submitted a couple of bug tickets for this. On republic side, I tried to do this mission last week, and the droids would not spawn. The next day, I came back and did imperial side, and the droids spawned. This week, I started the mission on imperial side and the droids wont spawn. I have reset multiple times, logged in and out, shut down SWTOR program and came back in. None of those attempts worked. I keep wanting to blame myself for this problem. I keep convincing myself I must have missed some step. However, I have done it successfully before, and I am doing exactly what is spelled out in guides and YouTube tutorials. Please look into this.
