This has been bugging me for quite some time now, but now that my savegame is growing beyond 10MB it's getting progressively worse.
Ever since patch 1.5, whenever I was in Solitude hold, I could only travel from an indoor zone back into the hold if the indoor area was the Blue Palace.

Any door close to the entrance would freeze the game in the loading screen.

When my save game started reaching 10 MB using carridges or plain old fast travel to solitude hold would start to yield the same result.
If I ever had to get to Solitude or a location near there, I would be forced to either do manual travelling or 'coc' to an indoor location in Dragon Bridge or of equal distance.

Now that I'm in the 13-14 MB range however, even those indoor locations cause a lockup when zoning into the Solitude region, meaning my only option now is to do manual travelling and NEVER EVER go indoor, because if I do, I need to COC myself back to somewhere FAR away from the Solitude region.


This happens with and without mods activated. At first I figured it had to do with the WARZONES mod, having some warzones very near and central in the Solitude region, causing excessive loadtimes, but that isn't the case.

Anyone got thoughts on how to fix it?

I should note that the freezing is more like an endless loading loop, music and the cloudy background continue to go fluently, but in taskmanager it ll tell me it's not responding.
I can leave it 2 minutes, or 2 days, it will just keep looping.

ADDIT:

I should also note that I've had 3 clean re-installs of Skyrim since 1.5, even swapped it to my SSD disk, and this issue keeps recurring.
