Oldish steeping grains

[Captain Damage]

I bought steeping grains for a nut brown ale about 6 months ago, had them crushed at the store and put them in the freezer for storage promptly when I got home. Between then and now I've moved during which time the grains thawed out and were at room temperature for two weeks before I got them frozen again.

Will they be okay to brew with? Should I just go ahead and figure it'll turn out to be beer anyway? Should I up the steeping quantities by nn% to make up for any magic lost while they were thawed?

Here's the recipe I'll be working with:
6.6 lb Liquid Light Extract
.25 lb Special Roast Malt
.25 lb Belgian Biscuit
.25 lb Belgian Special B
.25 lb Chocolate Malt
1 oz East Kent Goldings (5.0%) - added during boil, boiled 60 min
1.0 ea WYeast 1028 London Ale

I'll appreciate your advice and opinions

I've used stepping grains crushed and stored for six months at room temp with no problems. But I would not take it as a rule to follow.
