There are two padlocks that uses both the same date (january 4th 1845), but uses two different formats.
The first one is “maritime plus” (YY-DM-DM but reversed so: MD-MD-YY), roughtly translated into: “530014” (this is the solution for the first padlock).
The second one is trickier, because it calls in others date formats + other 2 date entries. in the end: the solution is always the same date from before (january 4th 1845), but it uses one of the new formats, named “paddle accademy standard” (DY-MD-YM), roughtly translated into: “040154” (this is the solution for the toilets’s padlock).
Apparently the game uses a WRONG combination for the second padlock (the toilet’s padlock). theoretically it should be “paddle accademy standard” (DY-MD-YM) for january 4th 1845, that roughtly translates into: “040451”, but apparently this isn’t the combination.
There is an error within the puzzle, basicly the developers mistaken day and month, in the code section XX-MD-XX, writing XX-01-XX (thats wrong, it wants the first number of the month “0”, and then wants the second number of the day “4”) instead of XX-04-XX, the second number of the second column wants DAY, not MONTH.
You guys should still use 040154 as the toilet’s padlock combination, but in reality is wrong.
