Really weird sub behaviour

Hi,

This is something I have not seen before. My opponent was "stacking" subs on top of each other and was able to move them as a pile - whats going on here?

This happens at around 25 minute mark when bobro sends stacked subs to my base. https://replay.faforever.com/21168632

subs have no collision, you can stack infinity of them on top of each other with shift+g

you can counter that by ground fire with a t1 bomber plane, if you catch the entire stack it only takes a few hits to sink all of them

Gotcha, thanks for the clarification
