Maybe the problem with medium hulls not showing up is that there is no scout predefined for medium hulls (means, a ship without any weapon tech). You must research some weapon techs before medium hulls show up, even, if you researched medium hulls before. But you can create own ships with medium hulls as soon as you researched medium hulls.

(or it is a bug which I never encountered...)

I'm getting an interesting change in the audio. Sound for the First Something videos has stopped playing, but star base management has a background sound that is new or somehow escaped my notice during hours of playing earlier releases.

Sorry to read that you are having sound issues. Do you mind sending a save to support so I can have a better idea of what is going on?

Currently we are working with Valve to try and figure out why this has happened. I will be glad to update as soon as I have more information.

I find that you get more immediate reponses if you paste the filename, line, and snippet of the offending xml.

Yes, in my case it were the remaining choices of a multiple choice event before.

Maybe it has something to do with the scale of the UI? I played on normal (second smallest)

In reference to seeing:

"Is anyone else seeing galactic event pages that are mixed up with ideology choices that you can't click?"

or

"Yes, in my case it were the remaining choices of a multiple choice event before."

Which Resolution and UI size are you playing at?

Is the unresponsive UI fixed in 1.12? I refuse to play another game like this

I would love to get this fixed. If you have any information and save files on the specific designs that contain this error it would be greatly appreciated. Is this issue in reference to ships downloaded in steam workshop or core ships provided by the game?

The whole of shipclassdefs is riddled with errors tbh.

The previous issue (where the wrong blueprint was used) was largely cleared up prior to 1.1, but there's still some examples of incorrect blueprints (line 3673, Altarian Ranger P uses FrigateP blueprint rather than RangerP blueprint) and other classes are missing hull definitions (all Iridium Rangers have no defined size).

is also related to that UI-size, when I changed to "small"-ui it was gone.

This will probably prevent upgrading the starbase module for anti-missile defenses:

StarbaseModuleDefs.xml, Line 1110: <UpgradesFrom>CounterMeasureModule </UpgradesFrom>

The extra space needs to be removed, as the module name does not have the additional space.
