I tried to collect flowers for minutes and nothing... All I get are errors saying "Oh No! We have no record of this floating item (161939)!"... And I'm sure I didn't open multiple tabs OR I'm in the last opened tab.

Just created the board because it hapened multiple times...

[edit]Just discovered the reason it happens... A bug buying things. I was buying Vesnali Coins massively, clicking in the item once and then pressing space like crazy. Even after stopped buying coins, more and more coins were appearing in my Inventory and my sP was being sinked for a while, counting pages and giving me the flower errors.

Not sure if it's something related to the new HHVM server, but I guess it's something to be looked into.
