[fixed/closed]Feast on the Fallen bad trigger

[Nexhro]

Describe the Bug:
Feast on the Fallen doesn't trigger at the beginning of it's controller's opponent's upkeep, if its controller's opponent lost life during the last turn.
It seems to trigger at the end of its controller's turn during which its controller's opponent has lost life, but doesn't do anything.

If its controller's opponent lost life during his/her (opp's) turn, it triggers on its controlelr's next upkeep, but puts a +1/+1 counter on each creature, including opponent's.

What exactly should be the correct behavior/interaction ?

It actually never triggered for me, regardless of when life was lost.

Bad values in "ct_all". Fixed.

[Nexhro]

Both bugs still occur in CoRM15 mini2.
