I am using ET to simulate binary neutron star merge.

I use NStracker to tracker the stars.

However, I found a lot of logs that likes : “New star location not set (18.4258,0.763088,0) because too far from old (15.0469,1.82812,0).”

I think maybe it shows there is some error.

Could you list some possible unreasonable uses that that can cause this error?

If parfile and initial_data are necessary, my parfile and the initial_data are here: https://github.com/yanyuechuixue/parfiles 

Thank you !
