HI
When I used destructive reach with my Sorcerer most of the times then enemy npcs get pushed/thrown into solid structures. Then they get stuck in the structure. like wall or mountain etc. This also happens when I am attacking an NPC on the edge of cliff and then it gets stuck in the cliff I am careful not to do this with boss monsters but I really think that QA department should really look at this bug, because it could disrupt a main story line for all.
