localGroup:insert and remove are crashing my code

I have some display images that I need to save after changing scene. So I put them in a table, created a global variable and put the table in there. But they still get cleaned if they are in localGroup, and when I go back to the global variable, the table is there and the keys are still the same, but the values are nil. This crashes my code when I try and reload it. I've also tried creating a newImage everytime the reloadImagesAndSettings function is called, but that screws things up as well.

Is there something I'm missing??

Here's my code:

local function saveImagesAndSettings()
        print("saveImagesAndSettings() entered")
 
        --setting global variable for future use
        _G["vars"].friendsUnfinished = true
        
        local tempTable
        if _G["vars"].friendsSettings then
                tempTable = _G["vars"].friendsSettings
        else
                tempTable = {}
        end
 
 
        tempTable[1] = kmf.photoEngaged
        tempTable[2] = kmf.photoWidth
        tempTable[3] = kmf.photoHeight
        tempTable[4] = kmf.maleFemale
        tempTable[5] = images
        
        for k,v in pairs(images) do
                print("Previous Image being made invisible: ",k,v)
                images[k].isVisible = false
                localGroup:remove(images[k]) --this SHOULD prevent deletion upon changeScene
                --kmf.removeListeners() is unnecessary because that's a normal part of clean-up
        end
        print("tempTable",tempTable)
        --packing away settings into a global variable
        _G["vars"].friendsSettings = tempTable
        print("saveImagesAndSettings() exited")
 
end
 
local function reloadImagesAndSettings()
        print("reloadImagesAndSettings() entered")
 
        --unpacking globally saved settings
        local tempTable = _G["vars"].friendsSettings
        
        kmf.photoEngaged = tempTable[1]
        kmf.photoWidth = tempTable[2] 
        kmf.photoHeight = tempTable[3] 
        kmf.maleFemale = tempTable[4] 
        images = tempTable[5]
        
        for k,v in pairs(images) do
                print("reloading Previous Image: ",k,tostring(v))
                images[k].isVisible = true
                
                --Simulate transitioning in with localGroup because
                -- inserting images[k] into localGroup makes them disappear
                localGroup:insert(images[k])
                images[k].x = images[k].x + contentWidth
                transition.to(images[k], {time = 200, x = (images[k].x - contentWidth) })
 
                kmf.initListeners()
                kmf.isActive = true
        end
