hey sorry but not sure if its this addon or something else, almost everytime i tried to copy a string either from wowhead, icy vein or anywhere, it kept saying importing from older version OR it says different specialization which is wrong as well.

copy example strings here, and add a screenshot

then i export the string:
"CUkBYC2NVjvWYmHkygUJeG83KuDpud6zDqRkuuSHorWgmZsNDzMjZwY2mZmNzMmZYGAAAAglZxMGmFmGYmhxG"
into your addon and it give this error, almost every string until i decide to open issue here to see whats wrong

interesting, I'll try it when I'm home from work
I'm pretty sure this addon doesn't touch any of the import logic unless you check the Import into current loadout checkbox 🤔

when I use that link and export, I get a totally different string: CUkAAAAAAAAAAAAAAAAAAAAAAAAmZMmZMMjMzMYYGbzMmZsNDzMjZwY2mZmNzMmZYGAAAAglZxMGmFmGYmhxG

if I put your string into wowhead or icyveins' calculators they both break (wowhead breaks, and icyveins just does nothing, you can see this by first resetting the tree and then importing)

so it's an issue with icy-veins, not my addon?

exactly same issue as u cannot import even in their own website =\ but ingame if i copy someone's string no issue.

you're saying it works fine when copying from other players
and the string is broken when trying to import it into wowhead/icyveins (so it's not just my addon)
and I'm 90% sure my addon isn't involved at all when using that import popup, but you can confirm it by disabling TalentTreeTweaks and see if it still breaks

when I export the link you sent, I get a string that's completely different (and seems to work fine), so it seems to be something weird happening on your end
maybe try a different browser and see if that helps?

to be clear, I'm not blaming you or annoyed or whatever, just trying to clear it up 🙂

i dont know this is an issue i encounter, i merely a messenger. if both wowhead and IV sites could not import strings into your addon properly, i dont know whose problem it is, and why no one raises this issue? it has been ongoing for awhile now and no i did both by import to current and also a whole new loadout. it just wont work.

when I click that, I get CUkAAAAAAAAAAAAAAAAAAAAAAAAGjxMjhZkZmBDzYbMmZsNDzMjZMGz2MzsZmZbmhZAAAAY2mBDjlNmkBzMMWWA
which is totally different (the first section is totally different, the rest looks the same)

I suppose you can try the wowhead discord or something, no idea where'd you ask for that, it looks like a strange and annoying problem..

edit: and trying to import that string you got into the wowhead talent calculator breaks, so definitely something weird going on

No worries. I disabled yours and then disabled every single addon and it still giving me the same error lmao.
u said its giving me a different string after i press export? lets try again
https://www.wowhead.com/guide/classes/demon-hunter/vengeance/talent-builds-pve-tank then click "copy Mythic+ Defensive build" 2nd last.
it gave me this string CUkBYC2NVjvWYmHkygUJeG83KuDpud6zDqRkuuSHorWgZsNDzMjZMGz2MzsZmZbmhZAAAAY2mBDjlNmkBzMMWWA

I tried different browser:
CUkBYC2NVjvWYmHkygUJeG83KuDpud6zDqRkuuSHorWgZsNDzMjZMGz2MzsZmZbmhZAAAAY2mBDjlNmkBzMMWWA

dawg something be wrong
