They never blamed JOIPlay for any issues, they only said that it isn't supported, meaning that any bugs encountered using JOIPlay will not be fixed unless the bug shows up on a supported platform. Don't go talking shit just because a developer is choosing to not support a certain platform for their game. It takes a lot of time to port this type of game (or any type of game for that matter) to Android, time that the devs have probably decided is better to put into improving this already incredible game.
So... If Joiplay reads Python... And the game has Python coding... Then it's the apps fault for reading Python Incorrectly? From my understanding Python is a computer language and either it's supported by all programs that read it isn't coded properly. This isn't "English" with accents and slang thrown in it is a universal computer language. If you read the trace back log the issue was that a variable wasn't defined correctly. Also I do believe that I mentioned if they did not want to take the time to port it that maybe they could ask someone who might be willing to do so for them.
