I may have missed it, but I haven't seen a response to this question yet. If no one has responded, it is probably because you haven't provided the code you used to run the simulation, or a reproducible example which demonstrates the problem. You say you didn't use set.seed(), but you didn't show what you did do, so there is insufficient information for anyone to be able to comment what went wrong.
