Spider Queen being out of map land area

A Spider Queen spawned from a level 3 spider nest and I had let her roam around since I'm Webber and she doesn't cause harm to me.

But then one day I saw her above and walking around the waters, and she couldn't get back into the land mass area as she walked towards it but was blocked to come in..  Sadly I'm not sure what caused her to go out there in the first place... Though all her minions that spawned just fell into the water with a plop. It was only her walking there.

I thought it was a location bug so I told myself I'll restart the game and see if she comes back on to the land.
Then I accidentally forgot about it and a few days after went back to check on her and now I have a spider nest floating on the waters.

I think I can burn it with a range weapon /fire staff or dart/ so I can stop more for spawning above the waters but I wanted to let you guys know that this happened while playing an Endless mode Don't starve together solo run!

I only use two mods, 'Geometric Placement', and 'Wisp, Wynter & Wei' character adds

P.S. I play from Steam but I couldn't find a mdmp file for my log ;~; sorry about the lack of information
