What is the bug?
The moves Doom Desire and Future Sight have odd visual bugs regarding move animations if the attack misses the opponent. If the move used at the end of the turn is a damaging move (and certain status moves), it is displayed as missing the target if Doom Desire misses as well.

In both cases here, I switched out during the turn where Doom Desire failed to land which caused the enemy's Giga Drain to miss (visually) since it was the last action in the turn.

My Claydol was slower than the Tyranitar, therefore causing Earthquake to display as if it had missed.
Are you able to replicate it? If so, how?

The setup is simply getting either of the future moves to miss and having the last action in a turn be a damaging (or other suitable) move. I could probably do some more testing and compile a list of affected moves in order to see what the pattern is, but I can't be bothered to do that at the moment. What's interesting is that the bug viciously drags the Pokémon out of its invulnerable state during Dive, for some reason.
I was also curious to see if the bug was present in Generation 4 as well, and sure enough:

Roughly the same thing, nothing majorly new - though it's interesting that it happens at all in a different format. When moving to Generation 5, however, I had two ideas I wanted to test out:
1. How does Sky Drop interact with this bug?
2. What would change if another Doom Desire was active on the same turn?

Desyncs occurred multiple times throughout the battle, such as Turns 11 and 16, where Jirachi would either not appear on one client or appear to be in a semi-invulnerable state.

I'll probably experiment with Gen 6 and beyond another day, if I'm able. I feel as if I didn't thoroughly test whether the interactions between Doom Desire and Future Sight were the same, but this is all I'll do for now. Pretty cool bug, spent a few hours messing around with it.
