Error MappedWater

[Felix-1000]

Hi, I am currently working with the LandTrendr.js and since tonight I get the following error message:
In users/emaprlab/public:Modules/LandTrendr.js
MappedWaterMappedWater is not defined

I checked and I think an error in Line 130 was added in the LandTrendr.js script:
//makes a global water mask
var MappedWater = ee.Image("JRC/GSW1_1/GlobalSurfaceWater"); //PETER ADD
// calculates water persistence 0 to 100 //PETER ADD
var MappedWaterBinary = MappedWaterMappedWater.select('max_extent').eq(1).not()

I think with MappedWaterMappedWater the duplication is too much

can anyone check this?

best regards
