Crash on splashscreen after patch

[InfidelKiller]

This happens after every patch.

Steam updated CK2 to 1.05d, I press play, I get the splashscreen and various "loading" messages at the top, then when it gets to calculating checksum, the game CTD and the icon is still in the taskbar. Clicking it brings up a black screen for a few seconds and then it crashes again. Verified cache through Steam and nothing else updated.

This is the error posted in the graphics.log file (I cleared the contents before launching again, so I know the error was generated on launch).
It may or may not be important. None of the logs held anything (except errors and that was just a missing graphics file - previously reported).

[provincetemplate.cpp:250]: Province 0 has invalid origin
[eu3graphicalmap.cpp:1872]: Invalid port location for province 1, center at 136,215, port location at 126.000, 277.000


Last time I had to completely reinstall twice before the game would work. I shouldn't have to do that.

Why is the patching process corrupting the game? Obviously something is wrong with it as a clean install (eventually) works.

I believe the first Steam distribution of the patch had a bit of a problem. Try deleting local content and then re-download the gane.

I applied the tried and tested Microsoft solution to everything: reboot.

Seemed to solve the issue.
Personally, what I think is happening is the patching process through Steam is locking one or more files and holding onto it, so at runtime the game crashes.
If you're lucky a reboot fixes it, if not it gets corrupted and then it's full install time.
