This problem may occur when you delete and re-add the operation - then the link from operation to sequence diagram will be lost. It can be caused also by the Fast Editor, which recreates attributes and operation after editing. I will analyze possible solutions and implement improvements, which prevent the problem you described.

Unfortunately, currently there is only one way - you have to manually select the method for the call again. I will work on improvements which avoid the unwanted unbinding of calls.

Thank you!
