Information about the objectives in this puzzle. (All objectives give +1000 points when fully satisfied, for a maximum of +10 000.)
Most objectives have a "Show" button which should highlight areas of concern in red. (Even when fully satisfied, objectives may highlight groups which may eventually contribute.)
Finally: a crash that can be reproduced (linux)
1) Load scientist-shared solution ss 24122
2) Select the ligand oxygen h-bonded to Tyrosine 37
3) Also select the carbon bound to that oxygen
4) Try and make it a single bond.
This crash should be fixed in the Dec 13th devprev release. (Thanks for the reproduction case!)
