Description
Mech clusters with Mech High Shield are always being hit with mortars, bypassing the shield.
Don't get me wrong, I hate the damn thing, but it kinda makes mech clusters too easy

Expected behavior
I expect the shield to intercept mortar rounds

To reproduce
Create new colony with 1 pawn, spawn a mech cluster using dev commands, make sure it has the high shield in it (active state).
Spawn 81mm mortar and shoot the shield

Screenshots & log dumps
Test setup:

Mortar rounds go through the shield unaffected waking up mechs and dealing damage:

Damaged mechanoid inside the shield zone:

Complete the following checklist
I hereby verify that I have done the following:

• [+] Confirmed that my game version and load order are correct.
• [+] Confirmed that I am running the appropriate and most updated version of Combat Extended and required compatibility patches.
• [+] Confirmed I am not running any mods with known incompatibilities with Combat Extended.
• [+] Disabled Combat Extended and attempted to reproduce the behavior without success.

P.S.
Without CE shells explode at the shield boundary:

Can confirm this, you can just mortar them to death (high shield in the picture is set to intercept non-hostile).
