Closing for now. If you still think its an issue in a month or two make a new suggestion. For now there is a good chance its just that people don't know the map well enough to get around it quickly.
Not so much a bug more bad luck. Looks like the anti stuck system detected you couldn't move and so teleported you out of the way, which in this case happened to be off the balcony
We won't be doing this. Part of the risk of a robery is how you split who takes the cash. Have one person collect and have everyone else defending - but if they die lose it all. Or have more people take the money so you dont lose as much if something bad happens.
