I got a bug report on my own mod of a crash caused by the combination of Planet Prismaris, Planetaris: Arig, and Barreling Machines. It was my mod that caused the crash, but while investigating it I discovered a bug in Barreling Machines.
When Arig and Prismaris are both installed, Barreling Machine creates a "sticky-sand-wooden-barrel" item out of Arig's pure sand (fluid) that spoils into a "sand-wooden-barrel" item. That item then is unbarred to produce Prismaris's "sand" (item). However, the recipe to do the unbarreling is never added to the corresponding technology, so it cannot be used.
Looking through your code (data-final-fixes.lua, lines 130 & 131), you have "spoilable-wooden-barrel" as the technology name its trying to update. However, the actual technology prototype's name is "spoilable-wooden-barrels" with an s on the end (data.lua, line 142).
