That takes a really long time on most simulators. Can you scale the test back
so it does this case before 35 seconds?  I can increase the limit if we need

Does it need 60 seconds or like 70 to hit the case? The default limit for erc32
simulator time was precisely 60 seconds of simulated cpu time.

sp04 I think is the one you are looking for.
