Failed to write spaceengineers.cfg - SerializableDictionary<int, ...> not expected

seems voxel hands settings break the config saving:

It's this one basically:

SerializableDictionary<int, SerializableDictionary<string, float>> VoxelHandSettings

STR:

1. Load any creative world that has voxel hands enabled.

2. Equip any voxel hand shape.

3. Press the voxel hand settings key (K default) and change any slider to anything.

4. Save world which triggers a client config too.

Now you have the above stacktrace in your SE log and any changes to the config will not save because it will error every time until game is closed.
