Affected Versions:
Quark 1.5-127
Quark 1.5-126

Using:

Auto Reg Lib 1.3-20
Baubles 1.12-1.5.2
Mantle 1.12-1.3.2.24

Several issues with Astral Sorcery occur on the two latest versions of quark.

Starlight infuser no longer shows items:

( There is an aquamarine placed in the infuser, but it does not show )

Lightwell no longer shows items, but particle effects still occur:

( There are aquamarines placed in all of the lightwells )

Breaking and replacing the infuser or lightwell causes the item to show for some time, and then after a while it is invisible again.

More information, this appears to be linked to the new feature "Items flash before expiring", which seems to be causing the items in the lightwell/infuser to flash and disappear after the timeout. Observing the items over a long period of time, the items eventually flash before becoming invisible.

Also setting the config option for this feature to false fixes the issue.

Oh oof that's a weird one. I'll see what I can do.
