so I’ve been working on a model for a while now, went into sculpt HD for detail but when i disable HD and try to save, zbrush crashes. If i stay in HD and save it works fine, only if I turn it off. So i tried turning it off, editing then turning it back on but it still crashed on save. Something else i tried was saving it as a tool and starting a new project then loading the tool but it still crashes. 
Edit: I’m willing to provide to project file if it helps
