It seems the distance from the target for the vampire feeding interaction has been increased, likely to prevent conflict with the Blade of Woe interaction.

This causes a few other issues, such as:

• It's now quite difficult to find the exact distance.
• It's difficult to use in interior spaces or places with obstacles.
• Being on an incline, slightly above or below the target, prevents the interaction from appearing.

These issues lead to some frustration when using the new feeding interaction, especially the last one.
