[Cobra]

additional info: when deleting a way, only the way is removed, the nodes are still there.

edit: after closing the dialog the object is still displayed and selected. Deleting it again leads to another error:

java.lang.IllegalArgumentException: {...} is already deleted

Undo is broken as well.

[bastiK]

Please update your plugins. If the problem is still there, see if you can find the culprit among the plugins.

[Cobra]

They are all up to date.
I'll disable one by one now.

[Cobra]

ContourMerge is broken.

[stoecker]

ContourMerge is not managed in SVN, so we can't do anything. You need to contact author.

[Cobra]

done, see github issue ​#1.
