In some mechs like the Victor, this rearrangement is unimportant, as the largest missile system is assigned to the hardpoint with the most slots, regardless of where it is positioned in the mechbay.
In other mechs, such as the Griffin and more noticeably in the Catapult A1, the missiles rearrange in every possible way except the way you want.
In example 1, notice that after checking out the LRM15 is switched from the top hardpoint which can hold up to 20 tubes to the bottom most hardpoint which only has a maximum of 10 tubes. This happens regardless of where you place the LRM15 before checkout.
I won't even try and figure out what ever is going on with catapult A1's, because how the missiles are arranged after checkout defy rhyme or reason, and even vary from one arm to the other.
For example if you have this load out on each arm
LRM5
SSRM2
SRM4
On one arm it will rearrange to:
LRM5
SRM4
SSRM2
and on the other arm:
SSRM2
LRM5
SRM4
Thus creating an unsymmetrical monsters.
