Corpse desecration is the sort of thing that would be added to a crime list, but it would not be punished.
Only the crimes listed under IC Rules are punishable. We'll make announcements if this ever changes or is different for an event. The only difference in this event is that if you commit a punishable crime involving a Sector 6 creature there will also be a severe hit to your character's rehabilitation points.
Assault is only valid if the creature requires medical attention of the hospital. You may assume this with the Hyena Wasps if you like. You'll need to check with us for Pilly since there is only one of him.
Being stung once or twice does not require a trip to the hospital, thus not resulting in "injury". If you'd like to have your character stung multiple times (within reason. Make sure you read the facts over and know why your character would agitate them to that degree or that it was the wrong place at the wrong time) then you can assume hospitalization was necessary. Or perhaps the effects of the sting caused additional injury. Like your character hallucinated and walked into a wall and broke their nose or something.
