Soul Drinker Passive breaks reviving ally
When Soul Drinker was 'equipped', we could not revive an ally. The player held down F for a few seconds to revive, but then the other person was not revived (as though the revive was cancelled). An undead spawns afterwards, which led us to realize it might be related to the passive as that passive spawns an undead after a 'bite'. Once the passive was removed, we were able to revive.
Steps:
1. Player A has Soul Drinker passive
2. Player A holds down F to revive Player B
3. Player B still dead, undead minion spawns
