SW Version v5.2.17 (I have reported similar for earlier 5.2 versions)
FGU 4.0.10 (Ultimate. if that matters, but similar has happened under earlier versions).
I have been having issues with applying effects groups and targeted individuals. I noticed that this has expanded to spell effects as well.
Issue 1 - Hitting the button for an Effect applies it to a random (well, at least not the intended target) if the individual is in a group. I have reported it before. If I have a group of 5 NPCs and its one of their turn (they have the little flag thing on them), hitting an effect button applies it to some other NPC in the group.

Issue 2 - This is newer to me - in the past if a caster picked a number of targets, you could hit the Effect button in the Power description and it would apply it to all the targets. This seems to have broken. It will apply it to the caster and some of the targeted. I thought it might be the same group issue (and in a group, one time it did apply it to the same guy multiple times in the chat). But the attached example the priest has targets both in a group and outside a group. It applied it to himself and one other in the group multiple times.
I have had these issues across multiple campaigns with different extensions and no extensions. This happens both with and without players connected.
