Patch 1.5 deletes all files in the "Mods" folder.

Mods that belong to maps are required to exist in that folder.

So BACKUP your mod files BEFORE patching to avoid data loss.

Thanks for your attention.

Wouldn't it be better to put this somewhere more noticeable? I feel like someone missing this detail could be in a lot of heartache.

Agreed; I don't even care about SC2 but this sounds important. Moving to Portal News.

If it had been a day earlier it would have saved my campaign.

When Ahli posted this I thought the same and wanted to include the warning in the 1.5 patch now live news post, but I noticed Ahli already had it in there with a big red box. Hard to miss really...
