Why fix the level if it's not even broken to begin with? As the saying goes, "If it's not broken, don't fix it." It's still solvable, and that's what matters! NL and SL are not the same engine, and it's ok if levels play out slightly different. This has been pointed out repeatedly. When keeping records for the minimum skills used challenge, there can be a note explaining why it requires more than 2 skills in SL, that the basher mechanics appear to be different.
Indeed, the basher keeps going on Lemmini and Dos, though the basher mechanics on SL and Dos appear to be similar in that sometimes the basher will stop on Dos as well. If anything, it would appear that it's a high-res issue, though the fact it keeps going in Lemmini says otherwise. So, it's likely the difference in basher checks that's the problem.
