If you drag any item onto Molecular Reconstruction Tool then the item will disappear.

Development Comment:
Thank you for the report. I and a few other testers tried to replicate this error, but items as they should just swap spaces, no items are disappearing. We will keep trying to replicate this error, if it’s possible could you provide a bit more information? Is the MRT in your inventory or any kind of storage? Is the item being dragged over MRT in the same storage/inventory?

Development Comment #2:
After long testing on multiple saves, we were unable to duplicate this error, just in case, I added additional checks to make sure that only items that CAN be merged will be merged. I will mark this as fixed but will keep an eye on this for future reference. Fix available in Midway Patch 11.32.
