I suspect an issue with Lua Core.
Someone in LS said all actions on non PC characters seem broken with GS, I haven't confirmed.
I'll confirm this. Every time I try to cure my Trusts the GS helper library throws some sort of error. I didn't check to see if it was actually still swapping gear for the cures. It doesn't appear to be a fatal error; I still swap gear with spells I cast on mobs and real PCs afterwards.
Trusts actions/damage no longer show in battlemod.
I've seen this as well. On top of that, cures cast on Trusts don't display either.

I also seem to have issues casting on Trusts when there are other people using the same Trust around. But I think that's been an issue for awhile. It was just really apparent while hunting narakas last night.
