Error after some time of playing

Hey there, I'm sorry to hear that this is happening to you :(

Can you please try running a pack check?

If the pack check doesn't find anything wrong with your Path of Exile files, can you please save your content.ggpk somewhere else on your computer, reinstall Path of Exile and copy the .ggpk file back into the fresh install folder?

If you continue to get this error after doing so, please delete the content.ggpk file and redownload Path of Exile.
