original scene had 100 frames and simmed fine, but I thought might be worth to see further development and changed scene length to 200. But resimming stops at 100 . Found I have to set output range to 200 by hand. Why does it not adapt to new scene length automatic like it does if I add a sim object at a given scene length ?

EDIT - just see there is another problem. Objects emit one coloured smoke. After they changed positions they can´t decide which coulour to emit and emit 2 colours all of a sudden ...
