1. It can happen, server 1 and 2 have slightly different times, and depending on which one you are you may find bidding discrepancy. I use server 1 (www) when bidding, and server 2 (www2) for just about everything else.
2. It shouldn't be back to 5: when you play CT, the enthusiasm is cut into half; when you play TIE the enthusiasm increases, but not to twice what it was...it's an increase of about 33% (estimated).
So you had 5, cut it to 2.5 (displayed 2), add a 33 or so %, and you have about 3.5
