Issue type:

• 🐛 Bug

Short description:

Similar to #99 but still exists in 1.12.2-1.5.6.

Presumably invalid logic assembly causes game to crash (see details below)

Steps to reproduce the problem:

1. Created variable structure ("Label": for readability)

• "FilterA": Inventory ReaderA.Items (List)
• "FilterB": Inventory ReaderB.Items (List)
• "FilterCombine": Concat(FilterA, FilterB)
• "Contains": Operator("List Contains")
• "Doesn't Contain": Negation(Operator(List Contains))
• "Filter Doesn't Contain": Apply("Doesn't Contain", "FilterCombine")

2. Add random items to the inventories connected to InventoryReaders A and B

3. Put "Filter Doesn't Contain" card in the "Export Items Predicate" slot of an Item Exporter.

Expected behaviour:

Export items from the network that are in neither inventory filled in step 2 (assuming logic is correct), or fail with a red "X" and explanation message (if it is not)

Crashlog

Same problem as CyclopsMC/IntegratedDynamics#644 (which has been fixed now), expect a new ID release soon.

Hmm, thanks for reporting.

It looks like operators are even harder to implement than they are to use.

Does this mean you can see where I screwed up my thinking? I'd love if you'd point it out. I haven't done much FP since college which was... quite some time ago.

No :-) (not as far as I can see in any case though)
What I meant is that the code that I wrote for implementing the operator system is quite complex, and it's the main source of bugs of this mod.
