Plugin data backup

Hello, my unreal engine decide another time to kill most data of project, but now i smarter - i have backup. So, project was backuped fine, but also i used plugin, coded with blueprints. Unfortunately UE decide to completely clear event graph of plugin actor by removing everything from there. Okey, i have autosaved copy of plugin’s actor - where i need to add it, to restore data? Where is UE - plugins folder?

kk, nvm, found it at /ProgramFiles/EpicGames/UE_version/Engine/Plugins/Runtime
