Garrisons not despawning

As per @Pumbler unknownpost in #memedia https://discordapp.com/channels/333343032328060939/370253862013239298/804208618911301694 
I found another 13 as I swept the shore line

UPDATE:
3 more garrisons have spawned in since my last post and each time I have recorded its behavior see below.
By the number of garrisons I've found now I would say it broke roughly 16-17 hours ago from this post.

• Garrison spawn in broken see screen capture (same as previous ones found)
• The GUI does not pop up in game when the event trigger is activated
• The event trigger does pop up in BM
• There is no yellow dot marked on the map when the event is triggered
• The garrisons do not despawn
• Appears loot and TC is not spawned in either. (however you can get ammo and guns from the turrets)
