Please include calculated distance to dropped head, and location of dropped head, in debug output.

Are distances 3D-vector or longest axis?

Please include which multiplier(s) were used to calculate reward, in debug output.

I will be able to give you the exact location where it is dropped. If in the air, it will of cause fall down to the ground.

I'm not seeing it. I see the multiplier = 1.5, but not that it was a far-shot (in this case).

Strange the name seems to be null for this multiplier, i understand that you complain :-)

normally it would look like:
[00:06:32 INFO]: [MobHunting][Debug] Multiplier: multipliername = 1.5

One of the multipliers names must be null... which is an error !

They are not null, but if you have cleared the name in your language file, you of cause not see any name :-)

Have you cleared the bonus names?

bonus.xxxxx.name=

Well of course! I should have caught that! Thanks.

Confirmed.

And the multipliers is already in debug information

The next release/snapshot will show the location in the debug information, when you use /mh money drop....

And the multipliers is already in debug information

I see the value of the multiplier that was applied, but not which multiplier was applied.

Yes, you can see which type it is
