Hey!

I have stashed all off my gear and other things in my home in whiterun. And i have heard on the forum that people have problems to come inside theirs houses after whiterun been attacked.
Which side should i pick, imperial or stromcloaks to prevent this. Or is this a just a glitch

I did the "war in Whiterun" quest section on both Stormcloak and Imperial (different toons). Each toon owned Breezehome. The house was perfectly fine at the end of that section of the civil war questline, no matter which faction.

Immediately after the attack there are shops that stay closed for a few days. That may be related.

I just did the whiterun attack as the stormcloacks, and immediately after the attack finished my house was still there, and undamaged, with everything in it.
I was too busy to try going into it _during_ the attack, but my guess is that that would work also.
