I've been having an issue with restoring pistons from backup recently.
I like to take a full webcore backup before I do any major development. This way, if I make any big mistakes, I can import that backup and restore the piston back to its old version. The problem is, I tried that yesterday, and it didn't work. It loaded the backup file, showed me the list of pistons it had, (correctly) marked them as already present, and offered a "Restore again" button by each. When I pressed "Restore again" on the piston I wanted to revert, it gave me a strange error about being unable to load the piston data from the backup. My backup file has no password.
Can someone try to reproduce this? I'm willing to help get any information you might need.
I am running my own webCoRE server locally.
