 ### Fixed
+- Fixed `NoSuchElementException` in spaces listing page when user is not defined. The error occurred when calling `user.get.id` on an undefined user in the spaces ownership dropdown. Added proper user existence checks in `listSpaces.scala.html` and `miniList.scala.html` templates.
 - Removed refrences to repo.typesafe.com from sbt-launch.jar and build.scala
