I did not expect it to help. For some reason your broyd2001 is corrupted.
The only reasons I can think are:
1) You have some NaN in the file.
2) You restarted with a pre-existing broyd* from some old run (you have to
delete).
3) Something else gave a NaN.
4)...
Unfortunately (or fortunately for me) I am on vacation, lying by a pool
with poor internet. If you can put the whole directory somewhere I can look
at it on Sunday or next week. I would prefer the whole directory so I can
look for the unexpected.
