This is for the new opt-in build pushed out Friday, May 13th. Binary version 126.96.36.199
In the ship designer, after you finish constructing your ship and want to save it, the dialog box no longer displays the tooltip for the choice of role (e.g. Assault, Capital, Guardian, etc.)
Hovering over the role don't bring up a tooltip anymore. I tried changing the role, and that doesn't trick it either.
