VS Player doesn't handle 0 Damage situations properly.

It says in Turn 1 that Forretress lost 1 HP, but the bar displaying its HP dropping wasnt there (in-game it dealt 0 damage)
Then in this one the same issue occurs, as well as an additional one with Metal Burst.

It doesn't display the "not very effective" message for Metal Burst. When you Counter/Mirror Coat/Metal Burst a 0 Damage attack, it's treated as a regular 1 BP move. Type effectiveness, Critical Hits, and Damage Rolls included.
