Translators Down
Due to a failure in the translators, any text sent from the chat members residing in other dimensions (TV Floor, Ojingeo, Rubisco, MIGU) came through as a bunch of squares. Each Test Block had to solve a puzzle involving the language barriers in order to establish communication. Afterwards, all of their text began to be translated automatically.
 * Delta: Ojingeo. Had to translate her text from a Korean-like series of symbols with the help of a Korean chart, then read the resulting sentence as phonetic English.
 * Gamma: Rubisco. Had to translate her text from runes.
 * Zeta: TV Floor. Had to translate her text from binary, then from Atbash.
 * Epsilon: MIGU. Used an alphabet of her own. Had it translated to English and learned it from there.

"Not a terroreyest"
After the Subjects mentioned Communism, TV Floor mentioned that's something considered terrorism in her home planet. Shortly afterwards, she mentioned seeing an unmarked van being near her place of residence and that "they knew". She then sent three messages in binary into the chat, saying it's a "meaneyengless message".

Test Block Eta
On September 23rd, the Sehans created a new Test Block: Eta. Volunteers from other Test Blocks have moved onto the newly made Eta.
