Bug, Energy after boss battles

I had noticed twice before that my monster was at negative energy after a boss battle.
Now I noticed that it went down from the 28 I had at the end of battle to 8.
That would make it minus 20 energy after a boss fight.
I don't know if that's accurate but, losing energy after being victorious doesn't seem like such a big deal.
I just noticed it and posted it in case of anything.

By boss do you mean god, or just regular bosses? Regardless, I've set it for all bosses to give instant 100 energy when you win... or lose.

When I first noticed I don't know if it was with a god but I think it happened with the nightmare ghost and the Heroktopus of which one time it actually went to negative energy.
I was paying attention with Bungle this time though. I had 48 energy and went to finish him with a Big Tackle and when I was back on exploring only had 8 energy.
Let me see what happens the next time or if anyone else has something to add.
But, like I said this isn't a big deal.

I stopped negative energy happening about 3 days ago, it is literally not possible to see it outside of the pve.php file. I'm not sure the problem with big tackle? If I remember correctly, it's 40 energy.

Vuala! I figured it out.
Yes, you were right Vael but it's not 40 for Big Tackle it's 20.
Okay, it happens with any mob when they die from a status effct.
If the last move your monster does consumes energy the consumption doubles.

I'm trying to get 200 golems right now so I was able to test it well. What ever the last move with energy consumption is, it doubles if the golem dies from poison.

Almost forgot, when I was fighting Bungle my Big Tackle wasn't strong enough so it died from poison. And there you have it.

Ah, I see why it happened. It had to do with (of course) changing the new HP system I did like a month+ ago. Thanks.
