this bug doesnt seem to be connected to this mode. this is the original Defend Castle mode which didnt have abilities like headhunter last time i played it. while its true i didnt play it in a while im sure you still meant the edited version of it, and since im the dev of the edited version im just goin to explain to you why that "bug" appears and maybe even why its actually not a bug but expected behaviour and why you might want to complain to blizzard about it so they finally give us more possibilities without having to waste tons of elements (there is a script size limit which is being hit real fast if you have to make workaround for small stuff like this)

1. The reason for why this happens is simply that the headhunter ability only applies to critical hits. but you cant edit the critical damage direclty, only the overall damage. therefore what the ability actually does is to trigger the Damage() function upon dealing critical damage. that Damage() function does not deal critical damage itself though which is why it doesn't count towards the headshot challenge.

2. why is it not a bug?
   well a bug is an incorrect or unexpected result, or and unexpected behaviour. it does pretty much what i expect it to do though and i know the only way around is to add more conditional code which then unnecessarily increases the element count and shouldnt be necessary.

3. sadly there wont come any other update for the version you just reported a problem for. atleast not from my side. anyone else can ofc feel free to pick it up and fix stuff. source code is available on github and on request you can even get a working ostw version of it

As for this mode. I'm not sure if Hukuta is still working on it especially with whats going on in the world right now. He wanted to make his own Defend Castle 2 a while ago but it doesn't seem like he found the time to do that yet (which is pretty much understandable)

Hello! Unfortunally I didn't develop (even didn't enter i know) last 6 months and didn't develop any updates.

I would like to finish my ideas but I don't have enough time for it, sorry.

Yes. I want to add:

• Brigitte (like Reins)
• Bastion (orbital artillery modification) - It deploys into artillery (like orisa + bastion) but shoots up a massive beam. The second beam comes from above in the castle area and chases the closest players to damage them.
• Echo (flying bomber modification) - drops Balls (Wrecking ball) on the road beside the castle. Dropping Balls are breaking on the ground and spawning a little squad of airborne assault (soldiers, widows, or something else)
• Echo (flying air fighter modification) - fast jet, flies and shoots to players
• Reaper (zombie modification). Btw I made a little mode (Left 4 Dead prototype, but didn't announce it). I implemented typical zombies using Reaper hero. He can chase and kick players.

I want to move some implemented ideas from my not-announced mods into this.

WOOOOOOOOOOOOOoooo lesss goo
