The following crash occurred when transferring items into a modular storage block:

As of yet no idea if it is reproducible or not. Will test further as soon as I have access to the system again.

I will check this out.

This is actually easy to fix. You don't have to rollback but you can use the next dev build and access your chest again. Hold on.

The issue should be fixed and you can restore your contents by using the latest version here:

Let me know if that helps and then I can close this.

Further testing reveals that I can no longer access the contents of the modular storage block at all. Attempting to access it crashes each time with the same error.

I may need to roll my world back in order to ensure the dimlets stored were not lost.

Hey man.

Thanks for the quick response and fix. It does indeed appear to have fixed it!
