I appreciate your explanation of the issue. I had attempted to update the 
z_mask in 
init_ts_info when the temp arg was reused, but it didn't seem to have the 
desired effect.
Since I'm not deeply familiar with the codebase, I didn't dive into all the 
details.
I'm glad to see that your new patch resolves the issue so effectively. Great 
work!

Thanks,
