Just had a crash to desktop, error log below. I wasn't doing anything at the time, just waiting on 10x speed.

Edit: After loading the autosave and playing past the crash point, the game is still running smoothly.

Dead link :(

I hate it when that happens.

Boo... I should have seen that coming. That's what happens when you rush a release. Thanks for the report.
Workaround until fix: don't use any civil act which says "converts X% resource to X" on a ship or station.

Alright sounds good. Thanks.

Fixed. Note that for the time being no resource conversion will actually occur on ships.

Awesome, thank you.

I've only tested this on star children but when attempting to build any ship design in a shipyard I crash to desktop or the game stops responding forever.

It's due to the shipyard having items that cost ore in its build list (motherships). If you mark all the designs that cost ore as obsolete and then back to normal, you will be able to build without crashing the game.
Interestingly, the game does not crash if you try to build a design that costs ore at first...
Even more interestingly, shipyards are the only builders bugging out. Motherships or staging hubs with the new construction yard module work as a charm.
I think it's a vanilla bug (or from RS, but I doubt it) as I have vague memories about having issues like this with superstructure hulls long before SoI even was an idea, and finding the same work around.
Well, now it's time to actually do something about it, though, with no error logs or minidump it probably is going to be a tough nut to crack...

I would love to give you an error log but the CTD does not generate one for me. Is a minidump something I could help with?

Thanks, but you can't help on this one. I had nothing generated on my side when reproducing the issue so neither will you.

Does anyone else have this game-breaking bug where the AI will suddenly just remain in their home system and never colonize beyond said home system. It happens so many times. It's annoying when your playing with few AI. Other than my experience with this game has been amazing until this bug bulldozed my immersion. Also are ship sizes (the model sizes) capped? I noticed they dont get bigger aesthetically which was my second disappointment. Really looking forward to seeing giant juggernauts. I do use the Star Wars ship models too.

I'm on this AI bug.
Regarding the ship size, it's not capped, but the model size scales less and less to the design size as the latter increases. The intent is to give a sense of immensity to stellar objects, which is done both by scaling them up and keeping the ship scale small. I am fairly limited with how much I can scale things up to keep the game playable so this is the trade off. The current ship scale formula is not necessarily final however and I already gave it a buff in the last version.

Mainframe effect range seems to be less than a single star system?

I haven't touched the range of mainframes I think. I'll have a look.
