Reflection question

There's one thing I don't understand about reflection bots. Every time the client is updated, it breaks the bots because the client has been re-obfuscated. But how do the bot creators find the reflection fields again?

Hope somebody can answer.
Thanks.

 

Debugging the values of each class I think

 

Damn, that would be boring to do each week or so, ha. But I guess that's what they do, listing the values and see if they change if you do a certain thing

 

If they had shitty client no1 would buy the auths, thats how they earn their money..

 

Obviously. If it's true that Nexus earns $40k+ a month then finding those fields seems worth the time.
