Ok, I have a feeling your first statement might be leftover issues with the white screen/disappearing info box problem. I was informed that the Credit Display is causing that error and that may be leading to other errors as well. That should be taken care of by Monday.
As for the 2nd one, that is always problem related to loading files from your cache. Since we've had a lot of updates and patches in the last couple days I'd recommend clearing caches again just to be on the safe side. For what it's worth, I have not experienced any of these issues while playing today, but I'll keep my eyes open.
