Group selecting tokens selects all polygon drawn lines on the same layer

Got a really frustrating issue here - Whenever I group select some assets (whether it be tokens on the token layer, things on the map layer), it also selects, and moves, ANY polygon lines made with the line or shape tool that are on the same layer.

For example: https://imgur.com/a/RK6MMni
Here I have clicked and drag a box over the torch tokens on the left to group select them. I am on the token layer.

The thing that happens is: https://imgur.com/a/fD7d6OB
You'll notice no box has appeared over the torch tokens and the polygon colour / size has appeared in the top left - because it has selected ALL polygon lines on the entire page instead of selecting just the torch tokens.

This is a major issue I've been encountering because it happens with the polygon line tool as well - if I try to select any lines I've drawn, I have to drag a box because it won't let me click on the lines.

But if I group select to grab a line, it grabs ALL lines on the entire page.

The polygon tool is so utterly broken.

Hi DM Steve, 

I was not able to replicate this. 
Could you supply a video showing this in action?

Which browser are you using? 
Have you tried a Incognito (Chrome) or Private (Firefox) tab?

I'm using Chrome - I've tried incognito and it doesn't change anything.

Here is a short video I took of the issue: https://youtu.be/VzvNTnGmiIM

That is very odd, and not typical behavior. 

Please PM me an invite, I'd like to take a look to see if I can figure out what is going on. 

Are you using groups? Is it possible you have some invisible object grouped with your drawings? Beyond that I'm stumped, without being able to get hands on, like Gauss is asking.

Hey Keith

No i haven't grouped anything neither !

Lemme PM Gauss here

Update: Entered the game, was able to observe the problem.
It did not appear to be a grouping issue as I tested it with all but one art object moved to a different layer. 
I was not able to replicate it by drawing new drawings. 

I did find a workaround though, send all the art objects to another layer, then bring them back one at a time. 
After bringing an art object back to the desired layer copy and paste it, then delete the original. Reposition the copy as desired. 
The copy does not appear to be affected by the problem. 

I have suggested that DM Steve send a link to a copy of the game to the Devs for analysis.
