error message on starting quest about sf-api

[the-marenga]

Yeah, that is because the 1-3 error message is directly passes through from the server, which only sees the modified (+1) value, so 4 in that case. I still think modifying the passed in values is overall more beneficial, as you can just pass the index of stuff, instead of having +1 everywhere yourself, so I am not changing that, but I agree, that just passing through the error is also bad.

The best way forward would probably be to just to do bounds checks everywhere and return a custom error, instead of the server error. I tried to stay away from that until now to make sure I would not accidentaly introduce false errors, or change the meaning of errors (connection error -> out of bounds error), but yeah, those error messages are for sure guiding people in the wrong direction. I need to fix that for the next release, thanks for the report
