were you saving at your highest subD level? did you have masks on your object when saving? system specs?

yes i was saving in highest subdiv but i have much higher ztls that this isnt an issue with. my machine shouldve been fine with this ztl it wasnt ultra high. and i dont think there were any masks while saving
system specs are
intel core i7cpu [email protected] ghz
9g ram
