Don't know if anyone had a look at the new (test) version of redactle? It seems to work differently from the current version.
In yesterday's game, #473, if you put 'state' into the guess box it only gives you each mention of 'state'. Whereas if you do that in the new/test version, it gives you every mention of 'state' and 'states'.
Not sure when the new version is being released.
