Thank you for the further insight! With this info, I now have tried using the “attach to” and parented the floor tiles to a beacon that is left at default scale, and so far it seems to have fixed the issue there in that one spot! I am going to try this on all the places that have parent relationships. Plus I will need to update the animation sequencer with those too.
Here is a screenshot of the editor and the floor tiles in game now 
I’m just wondering if this will be future proof for later updates or if a similar thing will happen but guess we’ll see! Thanks again!
PS. I was unable to get the original behavior to replicate, doing a test with 4 floor tiles unparented, 4 floor tiles parented to one of the tiles, 4 floor tiles parented to one default scale beacon device, and 4 floor tiles parented to one floor tile and all being scaled 2x. None of those tests returned the spacing / snapping gaps so idk how to replicate it. I did not test those with the animation sequences though.
