ok i have the problem as well

i just came back from my vacation .. i have today set as a vacation day .. i logged in and noticed some games had a few hours left .. the rest more than a day .. i made my moves in the game which had less than a day time left ..

everything is fine ... all my games have more than 1 day left and tomorrow (when i am awake) i can make the rest of the moves

i then went to my calendar settings ... i did change nothing .. i went back to the main page .. and now quite some games have -16 days time left

this looks weird .. and scared me a bit .. i will see what happens .. i have 23 vacation days left for the rest of the year and automatic vacation days on .. so if i have 22 vacation days tomorrow .. then 1 was taken away automatically by these negative times (although today was already set as a vacation day)
