Earlier today, i was playen tib sun on Grand Canyon, i was on the bottom right, and sadly yes, i was nod...... but what happened is that i was just messing around cause AI is stoopid, and i was just arty deforming the ground a few cells out to the left of my base. then i used a multi-missile on the same spot, and then it happened..... Weeds started growing like crazy from my massive crater! before i knew it, my entire base was vein invested, and all my buidings were KIA. Has anything like this ever happened for anyone?

There's a veinhole right next to the base location you were in, in the left. You must have not seen the veins (in case you had not removed the shroud by exploring the area) until they had grown into your "crater" and that way into your base.
