In one of my runs, I got core defense's key (core crypto key) got to corr and died.

After that, I talked in saloon to Viggie and interacted with Hacking post.

Game displayed in menu that core defense of - 4 resources is inactive.

I lost the next run before getting to Core, and now I am on the next one in Core.

In pause menu, Station map section - 4 resources is inactive, but in Game it is in effect.

All negative core effects are in effect, turrets take damage, no resource production and in negative stats in bot's room (visible in menu), all columns of negative effects look active.

New info :

After ending first area and getting too boss area - 4 resources become inactive.
