the viedos are a couple of hours playtime appart.

there was such a blob like this before right next to it turned into a biter base.
but the one thats still there issnt doing anything i hours now.

the modder issnt touching the behaviour so its something in the main game ( I was told )

Now ( after another couple of hours) the blob turned into a biter base

but still not sure whether it should take that long

I don't know if it matters, and nothing is breaking because of it, so unless it leads to something more critical, then I will say its not worth our time investigating
