Hello,
I have experienced this twice now. After an infestation occurs I usually leave up the hives to harvest some jelly and glowpods. However after about 1 day the hives disappeared. I killed all the insects, left the hives up, they would spawn a few jellies and glowpods, after a day they disappeared from the map. I was playing on B18 vanilla when this occurred.
already happened to me but after I created another colony these events will stop, it must be aogum bug in the game
Since A17 (I think, or maybe since A16) hives need to be maintained by the insects or else they will disappear.
@ TheGameOfThrows - You said you "killed all the insects", so it sounds like everything is WAD in your case.
@ G4
13L - Did you kill all the insects as well? Or are the hives disappearing even with insects maintaining them?
