Explanation:
Twitter relies on indexedDb, to store cache of user searches localy. BAS supports indexedDb, but has also old api webkitIndexedDB(which is removed it latest chrome versions), and seems like this old api conflicts with new one. It looks like twitter bug, which is present only on older chrome versions. It will work in BAS after chrome update, meanwhile you can use following workaround:
Solution:
Run "Execute On Every Page Load In Browser" with param
delete window.indexedDB;
delete window.webkitIndexedDB;
before any twitter activity(including page load).
