This level was tedious, but I managed to complete it because the mines don't always clip through the fences. Eventually, you'll get to the exit without being blown up by something that shouldn't be there. It's a grind, though.
Restarting the checkpoint had no discernible effect on mine behaviour, it appeared to be totally arbitrary.
Fix is at the end of discussion
Restart the Checkpoint (through the menu) to fix the glitch. Mines should not explode through walls.
