bug: Inspect AI implementation runs n+1 step before n step

[TheFloatingString]

I get the following error when running an implementation (mostly the same code) as eval/inspet_ai/scicode.py through Inspect AI:

eval/inspect_ai/scicode.py at line 172:

Exception: Generating problem 13 step 7 ahead of step 6.  

this is run on the test split, and the error seems to go away on the validation split.

changing the number of --max-connections has no effect on this error. This was run with openai/o3 as a model.
