Hi again :)
Found an issue where a penalty message appears (red text) when killing a mob (eg Skeleton) but a positive money reward is still correctly given. eg: You lost 25.84 Emeralds! but this amount added to the player balance (as desired). Just wanting to resolve the incorrect message.

Version: MobHunting-3.4.7-SNAPSHOT-20160907180800-B120
Steps to reproduce:

• delete config file
• restart server to allow MobHunting plugin to regenerate default config file
• change world-difficulty-multiplier from default value of 0.75 to 1
• change drop-money-on-groud from default value of false to true
• set game difficulty to 1 (easy)
• issue command summon Skeleton
• kill skeleton and observe penalty message

Hopefully this will reproduce the issue.

So I did something else.... I looked in the source code and examined the code where I write the message with red and then I think I discovered the bug.

The error only happened when the sum of multipliers was exactly 1 - this was not the case on my test server no matter using your configuration. (I had a rank multiplier as well)

So I made a small change to fix this. Try build 122 or newer.

Fantastic! Fixed!
Yes I am using Gringots but must have had something else happening to allow the bug to show. Anyway, gone now.
Thanks so much again. :)

Thank you for all the details. I have tried to do exactly like you, but I cant replicate the bug???

I see you use Emeralds? Do you use the Gringots plugin too?

So I enabled Gringots on my test server too, but still no luck, I cant replicate the bug. The text message is green and gives the right message.

I do not doubt that you can replicate the bug, but I cant fix it if I cant replicate it too. :-( So I need your help to find the root cause and when this happens.
