Coop hotfix #2

This hotfix addresses several issues related to reward distribution and mutation effects.

• Fixed self-damage when using the "Source" implant set.
  
• Fixed incorrect reward distribution in the "Meditation" and "Forge" game events.
  
• Fixed issues with reward drops in the "Roulette".
  
• Fixed certain mutations applying their effects to both players in a co-op session instead of just the intended one.
