The eldritch chain description states "The chain jumps to one secondary target per five caster levels [...]". At level 7, my eldritch chain should be jumping to one other target and was working as intended before the September 22 update. As of this latest update, eldritch chain no longer jumps to any extra targets and instead acts as a normal eldritch blast, hitting only the original target. This remains the same no matter what type of enemy is attacked - wolves, spiders, crag cats, skeletons, oxen, gremishkas, minks - and persists after crash.
