I'm not sure what triggers it, but several times I've come back to my world to see that all my requestor blocks have no recipe anymore.

I opened the block UI, put the block I wanted in (e.g. oak planks), set the number to 256 and hit save. The planks were made and things looked fine. Then later I come back to my world and the requestor is empty. Same things happens with all my requestor blocks (only have 2 right now - one for oak planks and one for glass).

Not sure what information would be helpful here.

Can't replicate in latest

I had some success using a chunk loader in the same block space that the requester was in. I'm not sure why that would be, but I know external storage attached to storage drawer controllers sometimes have trouble when restarting if they're not chunk loaded.

I think I've narrowed it down. It happens when I quit the minecraft client. I can quit one world and enter another, but if I quit the client, it loses the configuration.

This is a 1 minute video demonstrating the problem:

This is a link to an export of my mod pack with my world, mod configs, crafttweaker scripts, and logs. It should be importable with the Twitch client or GD Launcher.
