Ran into this weird issue where the big crusher seems to have an invisible entity attached to it, which can be seen when mousing over with a module inserter blueprint (from module inserter simplified.)

This causes (I'm guessing this is why) an issue where requesting modules seem to cause an immense amount of modules requested per crusher. Just this one test shows it requesting about 2300 modules for this small block of crushers. It must somehow think it can insert more modules than it can hold somehow?

Hi UltraJohn, I don't do any composite entity logic with the Big Crusher or any other entities. This is very likely the cause of another mod.

Oh gotcha, I'll look around for another culprit then. Thanks for the reply!
