everything but the biter creep can be restored by using "game.player.surface.regenerate_decorative()" in console. respawning biter nests does not cause creep to be restored. highly likely that the mod "decay configuration" is related to the original issue but removing it (or alien biomes) wont bring back the biter creep.
save 1 specific : the last location i was at when the bug reappeared is marked with
. the save given is from a a few minutes before the most recent occurrence.Update: save 2 is now made at a point in which running the command "game.player.surface.regenerate_decorative()" will result in the bug immediately reoccurring.
I can confirm that creep of newly discovered nests (which normally still exists if they weren't discovered when the last glitch had occurred) still dissappears when the bug reoccurs.
