i'm pretty sure you will be ok as long as nothing was frozen solid. certain compounds react differently to extreme temperatures, however i think you are going to be ok.

if potentially ruining the gear prevented you from going to jail then i would be thankful.

once again, unless they were after you in the first place her speculation is hearsay unless she could provide them with pictures or evidence to prove you had them. they aren't allowed to search your place without a warrant, and something as flimsy as her word is not enough for a judge to grant it unless she said you were some major dealer.

they might come by to question you, but you don't have to give them permission to search anything that is not in plain line of sight. if you really are worried i would seek legal counsel.
