Strange "locking" behaviour when used with The Furnace's function to drag folder of actors onto map

[DuskyVoltage]

This is a strange and specific issue, so bear with me.
The Furnace has a function where you can drag a folder of actors onto the map to quickly deploy multiple tokens at once.

When both Token Attacher and The Furnace are active, a strange behaviour occurs.
Randomly, but frequently, some of the deployed tokens will become stuck. Unable to be moved or interacted with at all, and upon restarting the server the token in question will be gone.

None of the tokens in question need to have anything attached to them, but the issue only occurs when both The Furnace and Token Attacher are active. (I've also tested with only these two modules active)

I managed to reliably recreate this issue by making a folder of a dozen freshly made junk actors then deploying them onto a map. I select all of them and attempt to move them, and one or two are often left behind and become stuck. (Though I've had instances where it's taken 2 or 3 folder-drops).

I looked at my createToken hook and I think this might be caused by me, because I'm doing something even though nothing is attached.
Besides this the issue is probably caused by a core foundry issue that is fixed in 0.8.x where a update can break another update on the scene. In this case I'm doing a useless update after a token has been created and this update can interfere with one of the other create updates. This is a race condition so it makes sense that it sometimes works and sometimes it doesn't.
I will remove the update when nothing is attached, but if you would do this with a folder with attached stuff it might break occasionally anyways until 0.8.x.

Nevermind I misread my own code. I'm not doing any updates so I wonder if the race condition is somehow triggered by my getFlag calls.
