Reasoning-heavy query hangs, but worked in a previous version

Problem to Solve

We have a reasoning-heavy query that hangs, but it worked fine in Studio Alpha 2.4.0 and returned answers in 2 seconds.

The query is

match 
$bank isa bank; 
$risk isa risk-score, has risk-level "high"; 
($risk, $bank); 

Proposed Solution

We need to investigate what on earth is going on here.

This issue is no longer reproducible, perhaps due to the various reliability improvements made over the last week.
