how to obfuscate liquidbounce
You are not allowed to distrubute a obfuscated version of liquidbounce, without sharing the source code of it.
Please read the GNU General Public License v3.0. (https://github.com/CCBlueX/LiquidBounce/blob/nextgen/LICENSE)
Of couse you can obfuscate it for private use or trying out code obfuscation, but I can gurantee that using ProGuard is not the best choice for Kotlin related projects.
It also does not help if you are just saying: "it will cause a crash". No one can and will help you with this issue. We are not the ProGuard forum or something.
