Especially for the CipherID – Part 1 challenge, the format warning also appears if there are not exactly 100 lettes of each of the 5 possible values in the solution string. This might have been the case in your first post. Maybe we should make MTC3 report this reason back explicitely.

Thank you for your quick reply. This is possibly the reason why I failed to submit an answer. But in the description of the challenge it has been nowhere mentioned, that it have to be exactly 100 of every kind of cipher (there is no reason that it should be exactly 100 of every kind). And when Cipher Id was a level III challenge it was not necessary to enter exactly 100 of every kind of cipher and it was also possible to enter other characters than S, C, P, V and H (for instance X for a still unknown cipher). I don't know, if this is still possible in the level II challenge or if only the five letters S, C, P, V and H are now allowed.

Anyway, the behaviour of the solution checking routine has changed without telling it to the solvers. This is a little disturbing at least for the solvers who had already worked on the level III variant of these challenge.
