I finally had a decent run at the challenge and we had 15 blights ready to go... The fourth ogre (near Oryx's spawn on the right) was at around 5% health when it teleported straight from its spawn point to the path next to me. Both myself and another Titan were using ToMs to kill the ogres and both were reloading so the ogre was not staggered when it teleported (from what I can remember). Suffice to say the ensuing chaos caused our last wipe for the night. Please investigate this issue and fix this bug. Thanks.
