T2-Artillery hits through shield without collision

[hex-5]

In the replay (19137039) at minute 10:44, the enemy stationary T2-Artillery shoots through a T2 shield without collision. Maybe it has something to do with the Jitter-Patch, which was introduced at this time. The bug could not be reproduced anymore, but happens all the time in the replay. Around the timestamp ~8:20 the arty also shoots engineers through the shield.

There's nobody named hex-5 in-game, I can't determine who the enemy is. Which side is having the issues?

The only engineers that I've seen being destroyed so far are these:

Which were outside the shield

Nice - this happens because the Aeon artillery creates a second projectile on impact, which can then occasionally pierce a shield

@Garanas Is this something that can be fixed?

[MrRowey]

@lL1l1 or @clyfordv can you see if this could be fixed ?

[Garanas]

The fix is to remove the 2nd projectile.

I have reproduced the issue XD:
