Cannot combine lines after opening JOSM after computer crashes

[anonymous]

What steps will reproduce the problem?

1. Computer will suddenly crash, and you'll need to unplug it
2. Start JOSM after opening the computer
3. Combine selected line segments, and a bug message appears.

What is the expected result?

The combine line segments must work correctly even after JOSM crashes.

What happens instead?

The segments must combine (including instances where messages appear).

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

Do you have an example file at hand, or two way IDs to be combined? It would greatly simplify debugging …
