relevant for doloadstate=TRUE, sediment=TRUE, routingmode=2:

suspended sediment storage of uninitialized entities was negative

- *.stat files are now searched in Output/, then Input/init_conds

 ### 3.6 Input/Output of state variables (optional)
-The state of (some) system variables can be stored in files. This allows their later analysis and resuming runs from them. Thus, any of these files can be generated by the model, and used as an input in a successive call. These capabilities can be enabled in ```do.dat``` lines 36-37 (see [Figure 1](#figure-1)).
-These files are optional. If not present, default values are used (e.g., 100 % relative saturation for the soils, 0 for most other entities). These files are expected in the WASA-SED output directory with the extension ```stat```. If present and enabled in ```do.dat```, WASA-SED loads them at model startup. It will then generate files with the extension ```stat_start```, that describe the status of the model in the beginning of the simulation (these should be identical to the ```stat``` which existed before). New ```stat``` files are written at the the end of each simulation year. .
