[AlokSwaminathan]

Checklist:

• Updated source's version for individual source changes
• Updated all sources' versions for template changes
• Set appropriate nsfw value
• Did not change id even if a source's name or language were changed
• Tested the modifications by running it on the simulator or a test device

Closes #753

seeing a crash when opening martial peak due to duplicate chapter identifiers. double check how you're assigning chapter ids and make sure they're unique, and make sure to test on device

I've been reading from mangademon with this version of the source for a few weeks, I have 60 from it and I haven't noticed any issues. What chapter on martial peak are you having problems with, I tested a few chapters on there and they seem to work for me.

interestingly enough, it's only happening when run on the simulator. none of the images load for me on device though. the culprit for martial peak is /chaptered.php?manga=1&chapter=3705, which I can see on the site is listed twice. this is their mistake, but you should probably filter out duplicates on our end within the source

I took a look at 3705 and it seems to work on my phone even though there were chapters with that number. I just went ahead and removed duplicates anyway though
