Trade 6 BAC runes with another player, and I don't get the traded runes

Today, I traded 6 BAC runes with another player for other ones, such as LITH, OHM, and JAH. He got my 6 traded BAC but I did not get the traded runes.
One of the things the player did, was split the runes stacks on the trade window, When I got the 6 runes from him, we lock the trade as usual, and then we accept the trade. In my case I never get the runes.

In my case the other player was surprised by the trade result, and he gave another of their runes as consolation and some Uber runs, but was not his fault.

But in the end, we lost the traded runes in my side, could you help me?

Had a similar issue - traded 4 Bac runes (full stack), 2 Kry runes (split stack of 8 runes, retaining 6 and dropping the split stack of 2 directly into the trade window), and 5 Moni runes (split a stack of 12 runes, retaining 7 and dropping the split stack of 5 directly into the trade window). The other player received the 4 Bac runes but did not receive the 2 Kry or 5 Moni runes, but all runes (Bac, Kry and Moni) were removed from my inventory.

I was the other player and can confirm. I got the Bac runes but not the ones that were split.

I assume you traded the again?

Made a second attempt with Zerstorung, this time splitting the stacks and dropping the split stacks into my inventory first before dropping into the trade window and it worked. I am still down the original trade materials.

Yes, we traded those materials again, but I am still down by the original lost materials.

Yeah, Eldahar traded me the two that were split a second time. Since they were not split during the second trade, it worked that time, but the ones lost in the original trade are still gone.

that’s so dumb that that happened to ya’ll…
