Environment details

• kancolle-auto version (last modified date): 6/15/16
• Viewer/browser: KC3 / google chrome
• Operating system:windows 10 x64

  Issue

Is the issue consistent (can be reproduced consistently) or is it transient (only happens sometimes)? Please check one of the boxes:

• [ ] Consistent
• [ x ] Transient

This has happened to me multiple times now, sometimes it happens and sometimes it doesnt. Kancolle-auto would just stop working when its trying to switch subs, I think it skips a click somewhere in here and cant find the switch ship button.

# to use a bucket if the OCR cannot properly read the timer, so adjust this accordingly. If you
# always want to use buckets, set it to '0'.
RepairTimeLimit: 0100

# (morale of 29 or below) the script will wait for a set amount of time for morale to recover.
CheckFatigue = False

# Whether or not to sortie when the port (ship slots) is full. Set to True if you do not want
# sorties to occur when your port is full. Port checking is automatically done when sortieing to
# Event maps, since sortieing is prohibited when you do not have 5 free ship slots.
PortCheck = False

LastNodePush: False

[Quests]
# Set to True if you want kancolle-auto to manage quests; False if not.
Enabled: False

# Quests to check for. Please check the Wiki linked above for a list of supported quests. Defaults
# to a list of most generic quests. kancolle-auto will ignore quests if they are not completable

@diceman112 This actually happens because of KC3Kai's subtitles, as they sometimes cover up the images used to match during the sub switch routine. The above update should keep it from crashing, even with subtitles enabled. Unfortunately the subtitles can still cover the portion of the screen used to ID whether or not the ship under repair is a submarine. These false negatives will make kancolle-auto wait for that ship's repair to finish, instead of switching it out. Minor inconvenience, but if constant combat is important to you then the workaround would be to disable KC3's subtitles.

@mrmin123 wow! Thanks for looking into my problem and directing me to the solution! maybe I'll try out KCV since I was using KC3 for the subtitles mostly

[mrmin123]

@diceman112 No problem! Honestly, I think with the above changes the chance of kancolle-auto crashing even with KC3's subtitles will be very very rare... The only thing I can't guarantee is the submarine switch subroutine properly recognizing that the ship in question is a submarine. You can also just disable KC3's subtitles when you're just letting the bot go. Just throwing out some ideas.
