The deletion of method parameters is not correctly recognized in the textual editors: After deleting them in the textual editor, the parameters are still in the graphical diagram.
This issue is more complex than it looks like. The whole handling of operations is broken. For instance, you cannot create two methods with the same name but different parameter types.

State calculation to consider the whole signature
Handle automated issue resolutions correctly (if operation and parameter creation keeps separated, the new state calculator will not find the operation anymore)
Think about quick fixes that allow adjusting operations instead of recreating them
