I held a DISK in my hand and ctrl-clicked it into a chest.
Steps to reproduce:
1. Start a sandbox scenario with nothing but DISK and base mod active.
2. Give yourself 2 DISKs and a chest.
3. Place chest.
4. Hold one DISK in hand, ctrl-click (or whatever you've bound Inventory Transfer to) on chest.
The mod DISK (1.1.0) caused a non-recoverable error.
Please report this error to the mod author.
