SCH Perpetuance + Regen equips

[yanosuke]

Initially I thought this was an issue on my end and my customizations, but after testing this out on a completely unaltered sch lua, it still persists.

The issue only happens when you use perpetuance and follow up with a regen spell (Regen V in this case). What happens is that it will equip precast and then midcast. However, it will immediately equip aftercast as well, thus not applying any gear potency/duration bonus.

The chances this happens seems completely random. Sometimes it does this, sometimes it doesn't.
Mostly when you cast regen V quickly after using perpetuance, but it sometimes also happens when there's a pause in between.

Again, this is an empty sch lua that just has the gear adjusted. Any ideas?
