bovada accepted my under bet then voided it after kickoff because line was “stale”.

so i put in an under bet right before kickoff and it went through, even got the confirmation. but then after kickoff they voided it and said the line was "stale". i've had bets canceled before but never AFTER the game started and after i already had confirmation. this isn't even one of those huge last minute line moves, it was pretty much the same odds for like 30 mins before kickoff.

makes me wonder how often this happens to other folks or if it depends on what side you pick. i mean, if i took the over and it lost, would they have still canceled it? stuff like this kinda kills any trust i have in some books. slots and live dealer don't pull this kind of thing, at least from what i've seen.
