Stained Glass
Added 2018-10-08 12:14:04 +0000 UTCI just streamlined the stained glass events, and those in the upper hall might have been given a new ID when i was doing this. If you want to be absolutely sure you don't lose any shards then I suggest waiting about using any in the Upper Hall until 0.74.
Saves from 0.73 to 0.74 will be compatible.
