I didn’t bump into the particular issue, but not being much of a Java person, they were very helpful. My bot was pretty consistent at getting lvl30 in a night and usually something fun like a snorlax or charizard.
When they broke the api I stopped playing, writing the code for a bit was more fun (for me) than playing as intended.
As an aside, are there games like that, which require writing code? I imagine the market isn’t big for those, but I sure had a blast for a month or two.
