Conventional start, real stars 1.9, upgraded to 1.9.3 in two steps. Preexisting condition: a pair of TechID-twinned "Tank Destroyer" designs – they don't seem to cause trouble and will remain until I replace the existing units with an upgraded version.
Minor glitch with the Select Name window. I cannot pin the condition down precisely. 1. I rename one thing, in case A: a ship design via select name (from themed names). Then I want to rename another – in case A: a system –, click select name, then change my mind and click cancel. The system is still renamed, to the name I had selected before, in case A for the ship design. 2. Followed the same steps (as far as I know) to reproduce, but couldn't. Cancel button indeed cancelled. 3. Case B: I *manually* rename a system body, then click and cancel Select Name for the system, system is renamed to the name I gave the body.
