Rarely, a race condition in which a USERNOTICE with a msg-id of subgift will come in before the submysterygift it shares a msg-param-origin-id with. This can cause unexpected behavior in multiple situations. Rather than try to force the submysterygift to always be sent first, I suggest adding a tag that marks a subgift as part of a random or bulk gifting in some manner. Even a boolean value would be enough for software to know to wait for the submysterygift to come in before processing the subgift. Otherwise, a forced delay is required on all subgifts, even if they're actually independent (direct gifts to specific users), to detect such hiccups, and that delay relies on client connection latency and Twitch server response time, both of which can be volatile.
