Thank you, Martin, for the reply. Yes, I tried building a new TAGS for #wfsuamgrad and it still failed to catch tweets from the two dates in question.
I have been checking my other TAGS and just found another that is failing to catch tweets. The TAGS for #amgradindy is not catching tweets for 9/20 to 9/30.
I tried making a fresh TAGS version, but since the Twitter cache has changed, it won’t cull anything farther back than 10/22, so I couldn’t say if that is a solution.
Any insights would be greatly appreciated. Thanks!
