⚠️

Important AFK Note for Hosts:

If the Host goes AFK during the preparation phase, the event will automatically disband. However, as long as the preparation timer is still running, you can fix this by walking away from the event location and walking back. This will re-activate the event so you can invite your friends again. If the preparation timer hits zero while you are AFK, this trick will not work and the event will close.
