Description

When attempting to "customize in meklab" on my Viking IIC (Standard) ID:3, I get an uncaught exception for ConcurrentModificationException (screenshot attached).

• Seems to only affect this Viking IIC
• Other mechs seem to work fine, I can customize them without error
• Tanks and VTOLs also have not generated exceptions (I am between contracts and was doing bulk refits in my downtime)
• The Viking IIC is still on the stock loadout, this would have been the first refit

To reproduce:

• Load Tempest Marauders campaign
• Hangar tab -> right click Viking IIC -> Customize in Meklab

Issue has persisted through a relaunch of MekHQ, so it should repro with the provided save file

As always, the bug report folder mirrors the mekHQ folder structure, you should be able to paste the contents on top of a fresh MekHQ install and it will put everything in the correct location

Files

Provide the .cpnx campaign file that this issue occurs in.
Provide any custom units that you are using in this campaign so that it will load on the developers machine.
Provide any other files that you have customized in this campaign like the factions.xml for example.
And provide the megamek.log and mekhq.log files for any NPEs or errors that MekHQ might be reporting.
Do not paste the entire logfile text into this ticket. Just attach the actual megamek.log and mekhq.log files
(Delete the above lines)

Issue appears to affect the standalone Meklab program as well, when I open the Viking IIC in Meklab it blanks the window.
