ArrayMaker / HashtableGetNext Error, Before FSMs Run

[memetic arts]

Greetings -

I'm getting a rather long error message that starts with a "Null Reference Exception" message on the HashTableGetNext action. The offending line, specifically, is used to assign the hashTable keys to an arraylist:

First, the variable to hold the arraylist is declared on line 62:

Code: [Select]

private ArrayList _keys;
Then, on line 106, where the error actually occurs, the assignment of the hashTable keys is made:

Code: [Select]

_keys = new ArrayList(proxy.hashTable.Keys);
The error isn't actually thrown until the point of hitting "Play", and in the Editor, the app will run and perform as expected with ZERO problem. (Unlike other errors that appear as soon as you save the code and won't let the app play). The only real issue, and why this has to be solved, is that I can't compile to iOS -- Unity complains that all errors must be fixed.

Also, I've set breakpoints on the very first actions that get executed, and the error is thrown ahead of those, e.g. as soon as 'Play' is engaged, and before any FSMs are run.

This app has already been released on the iOS App Store and updated several times -- it is only since going from free to "pro" and being forced to move to Unity 5.6, that this error started showing up. I've also, since updating Unity, updated PlayMaker to 1.8.4f5, as well as ArrayMaker, etc.

Any ideas/input would be greatly appreciated. THANK YOU.

Here's the error, in full:

Code: [Select]
