I've seen two new (to me at least) disconnect issues over the last 2 days, both with frightening consistency:
1) I have a Bag Stand Plus. If I change clubs or clubsets and then start playing a round without resetting my browser, I appear at the 1st tee without a club indicated next to the meter. Trying to take a shot under these conditions always results in an 'Unexpected Error'.
2) In multiplayer stroke and skins games, if a player exceeds the shot timer limit, someone in the group gets an unexpected error. After the trip to the lobby and subsequent reload, someone else gets an error & another trip to the lobby. This happened 4 times to me yesterday, results very consistent.
