[Wingnut601]

Expected Behavior

1. Place sand in smeltery
2. Sand melts into liquid glass
3. Pour liquid glass
   a. Pour into Casting Basin for block of Clear Glass
   b. Pour into Casting Table for pane of glass

Current Behavior

1. Sand melts into liquid glass
2. Pouring fails
   a. Faucets pour for about 10 ticks
   b. Other players cannot see glass pouring or poured glass in Casting Basin / Casting Table
   c. Logging out and back in with poured glass removes poured glass from Casting Basin / Casting Table
   d. Came back several hours later and smeltery does not show any glass has been poured (62 blocks, 428mb back to 64 blocks)
   e. Can not use fluid conduit to pour glass
   f. Visibly poured blocks can have other blocks poured into them
   g. Visibly poured panes can have casting plates placed into them
3. Forcibly poured glass cools into a visible block of pane of glass but nothing actually in Casting Basin / Casting Table
   a. Can not right click to remove block / pane
   b. Breaking Casting Basin / Casting Table yields only the Casting Basin / Casting Table
   c. Glass poured will eventually "return" to smeltery
   1. Poured a couple blocks and millibuckets - Smeltery controller confirmed this
   2. Closed the game, relaunched it several hours later - Smeltery shows 64 blocks of liquid glass
