Found out the issue, i also have the mod Big Enemies which also contains underground attacks and this seems to have been the cause of the issue.

im having the same issues where the underground attacks keep happens.

The situation is not reproducible.
Please provide your save with the "Underground Attacks" setting disabled and instructions on where to look for the underground attack that continues to occur.

gladly how do i send the save?
the attacks are constant from the north east side of the base.

Upload the file to a file-sharing service, such as Google, and send the link here.

Just in case, make sure you actually disabled underground attacks. I've encountered cases where players' map settings changes weren't saving. I don't know which mod is to blame, and I can't help.

here is the save zip

I downloaded the save and will check it over the weekend.
