Reproducibility: Haven't tried to reproduce it

After removing a tomcat 8.0.26 instance that my project was running on, I noticed several buggy behaviors.
When I attempted to close the IDE, I got a dialog that asked I wanna save changes made to file "server.xml".
This contradicts with the fact that I don't have such file opened in the editor, nor as part of my web project.

This is some of the steps I took before I got the issue.
STEPS:
  * removed the tomcat instance from services window
  * Opened project configuration (server for project is now blank)
  * Closed configuration without making changes and invoked "debug" run.
 

ACTUAL:
  1. got prompt that says "cannot save server". (screenshot attachment 1 [details])
  2. when closing IDE,  I got a dialog that asked I wanna save changes made to file "server.xml". (screenshot attachment 2 [details])
This contradicts with the fact that I don't have such file opened in the editor, nor as part of my web project.

EXPECTED:
  For (1), I should be prompted to pick server to run application on
  For (2), I shouldn't be seeing such dialog at all
