Did you overcook it? Overcooking will often cause eggs to weep not-insignificant amounts of liquid. You can see this trivially if you overcook scrambled eggs - you'll get essentially "egg curds in soup".
Products like custard powder don't come with a use by date, instead they have "best before". To be honest I see no reason why if kept dry custard powder would ever be inedible. Especially if it is just the corn flour and colour mix.
