So I managed to not save Meistr Siva in Act 2, didn't know that they would kill her.
I got a letter with a combination of the save in her house but I can't manage to open the hatched to go underground, any help?
The letter says:
15R 34L 23R 35R 9R 16L 33L 35R 51L 1L
Tried to do it in that order but that didn't work, am I doing something wrong?
