Crashing when opening crafting access

[VariableVixen]

Opening a crafting access caused a crash, when the following circumstances were all true:

• The storage network contained items, and was "aware" of them.
  • I had to break and re-place the heart to reset the network so it would recognise the items in my storage units. Without doing this, even though the storage units were full, no crash occurred.
• Recursion was enabled.
• The crafting access contained at least one crafting station.

Attempting to reproduce was successful once, then failed the next time. It is worth noting that the second attempt was different: I verified that disabling recursion prevented the crash, returned to the main menu, enabled recursion, re-opened the world, and attempted to verify the crash. This time, my game froze (which also happened in previous crashes) but eventually recovered. Opening the crafting access a second time re-froze the game. Changing window focus away and then back briefly unfroze the game. After multiple minutes, the recipes finished loading.

Since I was unable to reproduce the crash during my final attempts, I have attached the screenshot of the crash error message rather than a log file.
