puzzle storm restart

if I restart a run within the first few puzzles, I get exactly the same puzzles in the next run. I assume this has to do with the way the sequence is generated, but would be great if it would re-roll even if I restart within a short time.
Does anyone know how long this period currently is? I think its about 5 seconds.

Hmm, I don’t exactly know the problem. I, myself, have not done many puzzles on lichess, but I will check that out asap.

Sometimes I get the same 1st puzzle if I abort early. No other coincidences observed.
