NoSuchElementException during conflate

[marc_marc]

What steps will reproduce the problem?

1. I load 410k nodes in a layer
2. I load 700 nodes in another layer
3. conflate

if the data itself is needed, I can share it but I have no idea if it's a data problem or not.

What is the expected result?

a conflate :)

What happens instead?

popup with error msg

Please provide any additional information below. Attach a screenshot if possible.
