I found another BUG. Vasari mines (both explosive and gravity) use TEC mine explosion particle. Explosive mines should use Explosion_PhaseMine.particle and gravity mines should use Explosion_PhaseMineGravity.particle, but they use green Explosion_TechSpaceMine.particle.
Also gravity mine glowing animation is twisted - sparks should connect the spikes on the mine not just sparking in a side.
I hope this will be fixed.
