[Unexpected behavior] Catch a unique bloodsucker Thread - Old Good STALKER Evolution mod for S.T.A.L.K.E.R. Shadow of Chernobyl

Hey stalkers,

I'm facing some unexpected behavior regarding the "Catch a unique bloodsucker" quest in the Marshes (swamp).

Reproduction steps:

1. Go the the Marshes (swamp).
2. Go to Doctor (Dr. Marsh).
3. Start the "Catch a unique bloodsucker" quest.
4. Move to the bloodsucker.
5. Equip the "Doctor's crossbow" on your FIRST weapon slot (the upper one).
6. Shot the bloodsucker.

Expected behavior:
The bloodsucker is down and the quest updates.

Actual behavior:
The bloodsucker is attacking you, no quest update.

However if I equip the weapon (Doctor's crossbow) on the SECOND weapon slot, everything works fine.

I provided a save file for this issue:
Save game

After loading the save game: Just shot the poor fella.

The same issue applies to the follow-up quest from Doctor for the dog.

File version: O.G.S.E. 0.6.9.3 Final 2.0 with the OGSR engine

Happy hunting fellow stalkers
