Expression2 Lua error

[TreePyro]

Happens with an E2 that creates many holograms in a sequence of 200 ticks using tables to modify their colors, scales, etc. Timers are done via clk() functions
I can be contacted on discord at "thetreedemoknight" for more details and/or code.

sv: Expression 2 (shittlecan/Shittlecan_ED-FE25.1): Internal error 'entities/gmod_wire_expression2/core/array.lua:100: attempt to index local 'array' (a nil value)' at line 458, char 12

[Vurv78]

Send the code here, that can only error if some extension gives you a nil value for an array (which isn't correct)

    "basic" 
        -Has all standard attributes, including pos, clips, bodygroups, and submaterials.
    "Section":
        -Ignores "pos", "ang", "opa", "scl", "mdl" and "bgs" attributes.
            -"pos" is always vec(0)
            -"ang" is always ang(0)
            -"opa" is always vec(255)
            -"scl" is always vec(1)
            -"mdl" defaults to the base locomotive's model and cannot be re-defined by the user
            -"bgs" defaults to the base locomotive's bodygroups and cannot be re-defined by the user
    "Decal"
        -Ignores "mdl" and "sub" attributes, with an additional "mat" attribute.
            -"mdl" is always "models/holograms/plane.mdl"
            -Submaterials are not necessary for decals, since the model for them utilizes only 1 material.
            -The "mat" attribute defines the material of the decal. Note: Not necessary for "basic", since using the index 0 on submaterials does the same thing.
            
    Sub-objects:
    These are tables that exist within Object tables that define extra features about them.
        "bgs": Obj[X,table]["bgs",table][1,number]
        "sub": Obj[X,table]["sub",table][1,string]
        "clp": Obj[X,table]["clp",table][1,table]...
            ...["pos",vector]: Defines the position of the clip
            ...["aim",vector]: Sets the direction that the clip aims
            ...["ent",entity]: Defines an entity for the clip to be local to. Default is itself.
            
    Attribute index:
    "name": Does nothing on the paint scheme. Will show a customized name when doing .tell, recommended to put first thing.
    "pos": Sets the position of the object, relative to the base entity. Default vec(0), ignored by Sections.
    "ang": Sets the angles of the object, relative to the base entity. Default vec(0), ignored by Sections.
    "rgb": Defines the color, in RGB values, for the object. Default vec(255)
    "opa": Adjusts the alpha level for the object, with higher values giving a lower transparency. Default 255, ignored by Sections.
    "bgs": Modifies the bodygroups of the object. Ignored by Sections and Decals.
    "sub": Changes the submaterials for the object. Ignored by Decals.
    "mdl": Defines the object's model. Default "models/holograms/cube.mdl", ignored by Sections and Decals.
    "scl": Sizes the model of the object by ratio. Ignored by Sections.
    "clp": Adds a holoClip to the object. Should be formatted as Object[X,table]["clp",table][1,table]["pos"] with "pos" being interchangeable for "aim" for direction.
    "type": Identifies what type of object the Object is, between Basic, Section, and Decal. See above for more information.
