Rule 13.3 - Informational - bug/exploit reporting
Bugs and exploits must be reported in a timely manner. Since we often do things during events that are outside the realm of normal gameplay, bugs can and do crop up. Reporting them is extremely important during events to keep things running smoothly. Failure to do so may be considered cheating, and cheating can get you banned until the event is over, result in your event rewards being revoked, or worse.
