Plugin Deletes Itself

I dont know why but the plugin keeps deleting itself from my server its doing it to Npc Spawn too I dont understand why its doing it to just these plugins as everything else is perfectly fine

We worked it out....its to do with our "updater plugin" thats deleting the plugins not replacing them on restarts then I have to manually add everything back its actually annoying and for the first time in like 2 years I dont like this plugin
