I can write down how to locate the files if you have further problems.
Just look for the numbers 85 over 100. See the number 5`s those are the subs sensors....I changed them to 5. yours should read 85 over 100.
################################################## ###############
###################### Difficulty parameters ####################
# Note: difficulty is in range 0 - 100 with 0 being no difficulty (sensor doesn't exist) below the 5 are the Merchants values. I would not mess with them
# all the below get divided by 100 in code
# for non-merchants
VISUAL_DIFFICULTY_MIN = 5;
VISUAL_DIFFICULTY_MAX = 5;
HYDROPHONE_DIFFICULTY_MIN = 5;
HYDROPHONE_DIFFICULTY_MAX = 5;
RADAR_DIFFICULTY_MIN = 5;
RADAR_DIFFICULTY_MAX = 5;
SONAR_DIFFICULTY_MIN = 5;
SONAR_DIFFICULTY_MAX = 5;
# for merchants
VISUAL_DIFFICULTY_MERCHANT_MIN = 85;
VISUAL_DIFFICULTY_MERCHANT_MAX = 100;
HYDROPHONE_DIFFICULTY_MERCHANT_MIN = 85;
HYDROPHONE_DIFFICULTY_MERCHANT_MAX = 100;
RADAR_DIFFICULTY_MERCHANT_MIN = 85;
RADAR_DIFFICULTY_MERCHANT_MAX = 100;
SONAR_DIFFICULTY_MERCHANT_MIN = 85;
SONAR_DIFFICULTY_MERCHANT_MAX = 100;
