One from DW1.10 could probably work. Uses the ic2 pump in the middle rather than a cauldron. (copying from script could probably save you work). -V
Implemented! Spoiler: Recipe Please note that there is currently a bug with JEI and Minetweaker not showing the recipes correctly. This is fixed in an update to the CraftTweaker mod. If you put in the recipe but shows no output, click the output anyways and it will give the item to you.
Any idea if the spawn is chunkloaded by any means? seems to only work if there's someone at spawn, then the tank unloads and drains. -V
