saw a couple old discussions about this but they made barely any sense.

essentially, i keep going into the rock drake and wyvern nest on the northeast volcanic island, and i have NEVER found eggs. i've found the wyverns and drakes just fine, but they seem to all have gone off each other.
so, i came up with three possible things that could have caused this:
1) a bug in the map development
2) a mod is conflicting (shouldn't be, none of my mods modify eggs, dinos or spawns)
3) the draconis dinos have entered the final stage of a species in which they all mutate and become gay, ceasing all reproduction

which is it? who knows. looks like another job for mystery incorporated.
