BUG: Purge meter resets in co-op/Singleplayer

Game mode: [Co-op/Singleplayer]
Problem: [ Bug | Misc]
Region: [EU]

When you close and or restart a singleplayer game, the purge meter is empty.
Me and my friend have been building nonstop for the last 6 hours in a tier2/3 area (highlands near talitha’s island)
purge settings:
level 3
non time restricted
24 a day (default)
purge treshold 42k (default)
purgemeter update 3 (default is 15 minutes)

the purgemeter was filling up nicely and then when we closed it for dinner, and subsequently afterwards, started it up again… the purgemeter was empty.

Needless to say, we nevwr had a purge and we really want one.
