Why doesn't the restore point update with BCrypt hashes?

[maykelbembibre]

Not a bug, your wordlist is too small (198172 candidates), there's simply no restore checkpoint possible with it.

I don't understand. Here is an example with a task using a large word list which had been executing for 4 days:

Code:

In those 4 days, progress had advanced up to more than 28 millions of combinations. There wasn't still any restore point. What could be the reason for that?
