Does anyone else have a problem attaining Masterful?

[bluphraust]

I have done this three times now and still no achievement. I don't know
how much longer I will function as a normal person if I have to do this again.

Is it possible this achievement is bugged/glitched? Has anyone else had a problem getting this?

Does it have to be done in one sitting?
Is there a cache clear and load trick to get the achievement to pop?

i just got it the other day. it does not have to be done in one sitting.

i kept a list on a piece of paper to keep track of my progress. to stay organized write down all stages and leave some space in between each, and when you beat a stage write down the character you beat it with next to the stage.

when you beat each stage with all 5 characters it should unlock!!!

Make a list before you start...
This achievement took me several attempts...
because I was not organized from the start...

Not sure how many times I had to replay levels, because one of the first ones I completed I marked the wrong person (although 1 was 99% sure I marked them right)

Started a new list and had to go through most of them again.

So you need to beat each stage with each character? I was afraid of that...

This blows...

I followed the guide. I used Sandy for Bronze, Crabs for Silver, Bob for Gold... then ran through with Pat and Plankton... NO achievement. I take it by what everyone is sayingg, there is no way to check which ones were done. guess i have to make a spread sheet... lame.

It takes a while yes, but is totally do-able...
