In the current Legendary Overlords event, I hatched three eggs at the same time. Varuna, the Warrior and iMigbo. I get 160 points instead of 180, so one of the three is considered "breedable". This has to be a bug.

So which of the three is it? The only thing I can think of is that in some past events, one of the three was breedable for three days, so it was "breedable". With so many temporary breeding events (about one per week?), how can I keep track which of the previous non-breedable monster is now considered as breedable, for a particular Legendary Overlord event?

Varuna is in a breeding event right now. Parents become breedable when in such events.

When I put Varuna into the hatchery, which is 2 days ago, the VIP breeding event has not started yet. If something like being breedable can change in the middle of the Overlord event, or in this case, 40 monsters becomes breedable (with parents, jokers for 9 combos) at the end of the Overlord event, how can you plan anything?

You could have the results of 4 hatching and 4 ranking be marked different from what they used to be at the start of the event, and what points you can expect from them.

Hey don't shoot the messenger...

This is in the bugs section, and it should be considered as a bug. In Monstergram, there is this indicator on the upper right hand corner of every portrait, indicating if a monster is breedable, or teamshop, or elite, or WarMaster. Why is such a clear indicator which is already in Monstergram not being used for the Overlord event?
