Stack Overflow Error in Blueprint

Thanks for the reply. I’m really struggling to hunt this problem down though because I haven’t been able to replicate it on my end or in editor despite it happening for multiple play testers on different machines. Do you think this problem is most likely caused because of the size of asset or by the actions performed by the asset?

These blueprints are puzzle pieces which use interfaces to pass arrays from one to the next, each doing simple math operations on the values in that array which can vary in length from 6 to 12. The player can also pick them up and reorder them.
