IllegalStateException merging nodes

[skyper]

What steps will reproduce the problem?

1. load attached file​
2. unglue way 27019525 from node 296167882
3. merge the new node with node 2374719155 by moving and holding Ctrl

What is the expected result?

Nodes are merged

What happens instead?

IllegalStateException

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

I did quite a lot of reverting, purging and merging with this layer. Probably around 25 data layers.

Problem seems to be that I did undelete the node I unglue from and the new node also has the attribute "deleted on sever"
