UndertaleModLib.AddAssetsFromList() return NullReferenceExceptions

[CoolModder]

Describe the bug

When attempting to save edits to code of mindwave demo, it returns:
System.NullReferenceException: 'Object reference not set to an instance of an object.'
At line 209 of Compiler.CS;
Modifying the assembly works as intended, and in fact the code will be decompiled as the intended decompiled code
Original decompiled code (gml_Object_obj_charselect_menu_Create_0 of Mindwave):
characters = [charselect_tutorial, charselect_shuffle, charselect_sparkle];
Original disassembly:

pushref.i gml_Script_charselect_shuffle
pushref.i gml_Script_charselect_tutorial
call.i @@NewGMLArray@@(argc=3)

Intended decompiled code:
characters = [charselect_future, charselect_tutorial, charselect_shuffle, charselect_sparkle];
Intended disassembly:

pushref.i gml_Script_charselect_shuffle
pushref.i gml_Script_charselect_tutorial
pushref.i gml_Script_charselect_future
call.i @@NewGMLArray@@(argc=4)

Appears to be due to arrays not being recompiled properly

Reproducing steps

1. Open Data.win from Mindwave demo
2. Replace the original decompiled code from -> gml_Object_obj_charselect_menu_Create_0 with the Intended decompiled code
3. Save or switch tabs

This also happens when trying to import .gml files with arrays, with the same exact failures
