Hello, after updating the mod, the following error occurred:

Mods to disable:Failed to load the following mods: bobassembly/data-updates.lua:7: ...ssembly__/prototypes/chemical-mixing-furnace-updates.lua:65: attempt to index field 'chemical-boiler' (a nil value)
stack traceback:

I see it, Will fix.

I'd say you need to turn off Assembly limits to make the error go away, but if you load the game without the mod enabled, the option to turn them off will go away, so you're only option is to wait until I fix it, or delete your mod-settings.dat file. (Deleting the file restores defaults)

same problem right now..

There is a newer version than 18.6 now, you know.
does it still happen on the newer version?
