Be nice if it could work but then again do you want people to have this thing on the back of a quetz just picking up all the eggs after a simple fly by? Maybe an INI setting for it to enable for single player funzies. Or even server events that may disable wyvern spawns and then turm them on for a limited time. (our server does that) and have it be a free for all to grab em.

Seems to pick em up just fine if you have a mod that lets you breed them or you already picked them up for us
