based on the description, above, i was not able to reproduce the reported behavior. at the present time, both mode yield forty-four solutions:

Yes now I also get the correct result. Arto, did you observe the difference though? Maybe this could do with caching? I noticed this soon after importing a new dataset.

[artob]

@pumba-lt no, sorry, I couldn't reproduce it either. If it should reoccur, please capture the outputs as well, that might contain some clue.

[lisp]

if it was a specific sequence of operations which yielded these divergent results, the best way to capture them would be a script which starts with a repository with readily enumerable content and goes through the steps to reproduce the results.
