Error loading mod? conversion of data to type "j" failed

[vzybilly]

I'm not really to sure what this error is but the output line is

Code: Select all

  19.159 Error Util.cpp:43: Error while loading entity prototype "vzy-compressed-accumulator-3" (accumulator): conversion of data to type "j" failed

I'm not even sure how to start debugging it since it's hit after the data-updates.lua so I'm at a loss...
