Description of the bug

CAS protection layer keeps getting re-enabled without any input on my side other than opening the map. It was a bug a while ago, that was eventually solved, but now it's reappeared

What's the difference with what should have happened?

Overlay shouldn't toggle on without me toggling it on.

How do we reproduce this bug?

0?) Join live server? (maybe doesn't bug out on local)

1. Open map.
2. There is CAS protection layer.
3. Disable the layer (need to click it twice because the game thinks you have no layer on).
4. Re-open map again.
5. There is CAS protection layer again.

Related to this: TacMap drawings also regress to not showing.

See closed duplicates for extra information that don't point out the cause of the TacMap losing tracking and not fetching the right update information to send out to things.
This happens at somepoint during the round. And might not actually occur. So who knows why or how it happens yet.

Of note for #12946
Showing outdated positions is it losing correct Z tracking which was an issue that existed before this.
