It reproduces sometimes successfully. I think it's associated with the X Marks timeout reseting.

Repro:
1. Pick any hero with 6 full Satanic.
2. Move to somewhere or channeling.
3. Cast X Marks the Spot on it.

Result:
The hero would neither be teleport to the position and stop nor be interrupted.

Expected:
The hero's any move should be totally interrupted as in the normal case.
