Okay, so all I am trying to do, is just have a forward operating base (FOB) near a plains biome, so I can get some lox, make a lox cape, and then try to defeat modor and then I can smelt black metal that I am slowly gathering

Only problem is, a deathsquito aggro'd when I was chopping some trees, didn't think their range was that far, so my plan was to just retreat into the base and close the door.

Well, my timing on closing the door didn't work, the deathsquito got inside the base, so I closed the door and went outside and ran into the black forests.

The deathsquito didn't seem to want to attack anything in the base, in fact I think this might be a bug (unintentional pun), but yeah I think I messed up its pathing and AI when trapping it inside

I later went back to my base and opened the door, and again...ran like hell into the black forest. I ran so far as to get back to my other base, that is nice and peaceful, in the black forest due to my various base building methods

Now, I have returned to the FOB I had, with the deathsquito, it's still there--I portaled back to my FOB inside the base, and heard the deathsquito outside.

The base is built on the black forest biome.

Will this deathsquito eventually go back to its normal "patrol area" and regular pathing, or will it be permanently aggro'd? How long do I have to stay clear of the base?
