@sakalouski Do you have code I can run to reproduce this error? It's hard for me to figure out what's causing this error without being able to reproduce it myself.

[evhub]

@sakalouski Also, try updating your BBopt (pip install -U bbopt) and seeing if the error is still there--it's possible this error has been fixed in recent versions.

[sakalouski]

It was the same code as in the other issue. I got it after 12 iterations, which is weird. I used the last version of BBopt

[evhub]

@sakalouski This error should now be fixed in the most recent version of BBopt! Just pip install -U bbopt to get the updated version.
