Breach and Lag

Started a breach in Mesa tower, it immediately started lagging, my character and the mobs started jittering back and forth. I hit escape to pause and things leveled out. Ran the breach like normal and lag hit again and I got rubber-banded back to where I started the breach. The breach closed and I only got 1 breach splinter and all the items that were on the ground from the mobs/hands vanished. I did keep everything I picked up during the breach though. I do sometimes have lag but I have never had something like this happen, it was more than 15 second rubber-band, and I have never lost loot like that, it just vanished. I did check filter to see if it filtered out everything and nope, items were gone. Feels like the new breach splinter mechanic is susceptible to lag, I should have gotten more with the number of mobs killed and area covered.
