Fate Egg hatches twice on the opponent's screen. This has no actual impact on the game, but may cause some bugs.
Most of all:
- Placement Errors -> Desyncs
-- A creature appears in the wrong slot.
- Immaterial Status -> Desyncs
-- This is hard to recreate, but it exists. When a Phase Dragon is hatched (twice), the copy dies, emptying the slot. The first creature to enter that slot will now be immaterial.
- (Not seen) Death Effects -> Desyncs
-- Untested.
This bug can potentially cause desyncs, and I think it should be top priority.
