This is a workaround.  Checkout the new fix.

This disables the control, i.e. no results are returned, and an error is
issued.  What is the behavior you get?

This has been fixed few minutes ago.

regular searches:
soft limits: activated if no explicit limit is requested (e.g. -z, -l)
hard limits: activated if explicit limit is request (e.g. -z, -l)
unchecked: based on estimated candidate number (regardless of -z, -l)

hard must be >= soft

paged results: by default uses hard limits; regular hard limits
can be overridden by prtotal.

Same applies to time limits, but apart from hard and soft, other
limits are meaningless.

I'll check that.  Thanks.

I fixed the prtotal bug few minutes ago.  Sorry for any inconvenience,
and thanks for testing.
