Oh wow, never thought it was bad to make people aware of a bug that shouldn't be there in the first place. :I

Making others aware of things so that they can abuse it themselves is not really what you should do.

Instead, report the bug to nutaku so they can work on fixing it.

This whole deal comes from the fact that they made stamina only be used up when a mission finishes to begin with and they are actively monitoring to only allow a certain amount of resets per hour/day/whatever before they consider it abuse rather than a random disconnect.
