Today I was told by horst35 that there is an error in 4/31. The riddle's solution is case sensitive (which is intended), but whereas the expected solution ends with a lowercase letter, the riddle itself gives an uppercase letter.
@All: If you already got some reasonable solution in the past, but it was not accepted, please try again with the last letter being uppercase.
@Sphinx: Please make it that the server accepts (only) the solution ending with an uppercase letter from now.
Sorry at everyone for that mistake.
