Lo-Fi Games

Well,

I have a small base, i want to expand but can't.
I expand the walls with a new gate... It's ok.
Now I remove one superfluous wall... I have a wall termite problem.

I have included a save with the problem.
Try to remove a wall near the inner gate to see termites coming.

After all these updates with wall termites bugs squished, i wanted to retry my base...
But the same problem appear, remove an inner wall and wall termites comes.

I don't know if it's a save game corrupt or something else

And the problem appear when I import the game too.
