📋 About This Mod
**WARNING**: Disable Cobblemon! Keep it disabled! Launch the game again after it's first ever launch with this mod. This mod intends to make 1.20.1 (https://modrinth.com/mod/cobblemon) compatible with other mods that rely on a newer version of Kotlin than Cobblemon was packaged with. If you are using other Cobblemon Addons disable them, launch with this patcher enabled, read the popup, and then ONLY reenable them. Do not enable any Cobblemon main mod jar. **WARNING**: I am a total newb at Minecraft mod development and this is likely a poor solution but it works! Hopefully... What it essentially does is automate the deleteing of two Kotlin folders within the Cobblemon.jar, allowing for a newer version of Kotlin, likely from (https://modrinth.com/mod/fabric-language-kotlin), to take it's place. This can be done manually without this mod but I wanted to make things as plug and play as possible for my friends. The original reason why this was made was to allow (https://modrinth.com/mod/create-fabric) (https://modrinth.com/mod/estrogen) and it's dependency, (https://modrinth.com/mod/cynosure), to work with Cobblemon. If you need help or find any issues my Discord is tsubameuwu.
