Yea I had never heard this rumor either of them both dying. That sounds absolutely horrible.
Yeah, I googled a little bit and couldn't find the information in English, so I'll write about it here. It's quite a long time ago and the Japanese internet tends to not archiving data well (coz that information was circulated on 2ch). So as the 1999 series was catching up with Togashi's hiatus, the series's director Kazohiro Furuhashi decided to end the series right there with his original written ending. He sent the screenplays and storyboards to Togashi and the manga publisher. There were going to be two episodes:
Episode 61 Avici x Calling x Requiem (阿鼻×叫喚×レクイエム)
Episode 62 Red Eyes x Silence x Catastrophe (緋の目×沈黙×カタストロフ)
We don't know about the details too much but in a board summary, Kurapika ended up killing Kuroro, but as Kazohiro liked to input his moralistic "eye for an eye" view Kurapika has to die too to pay for the price. He died laying in Leoreo's arms.
Of course Togashi rejected this ending vehemently, and for the people who knew the manga well knew this is definitely not Togshi's style (his ending would be way more anti-climatic, non-endings, and got the lol/wtf vibe...that's why I think he rarely takes HxH that 'seriously'.)
The screenplays and storyboards for these two 'phantom finale episodes' was auctioned off after the TV series was over. It was up on the Japanese Yahoo!Auction for a day and was sold for 81000yen, in which you can see there were 3 images
Basically Kurapika was Furuhashi's Mary Sue. He mentioned in many occasion that he sees Kurapika as a 'tragic heroine figure' and that's why the Yorkshin arc in 1999 series took a dive and deviated from the source material drastically in terms of focus, tone and core. It's almost like fanfic. Strangely that it seems like a consensus on 2ch that Furuhashi doesn't 'get' Togashi's style at all, and he liked to impose his own views/style on things he adapted too much...but of course there're so many fans who prefer Furuhashi's re-interpretation of HxH as many found the
tragic heroine Kurapika very 'moe', and prefer the dark and take-itself-too-seriously melodrama.

Who are you even talking to? If you're talking to me I'd rather you just drop it. As for it being insulting. Are you referring to my calling him a troll?
Relax mr.sticky

, Uriel was talking to that mousiehamster user, who asked why his posts kept on disappearing. That 'asking why my post was gone' is gone again so it appeared now Uriel's reply came after yours. I saw his post this morning but it's now gone, Uriel's post was not addressing you.
