47.15 Infinite loop after hitting Start Mass Repair/Salvage?

[gsparks3]

Environment

47.15
Windows 10
Java version 11.0.8

Description

MekHQ locked up after hitting "Select Active Units" and "Start Mass Repair/Salvage". Buttons in said menu are no longer responding, but program overall is not listed as Not Responding. CPU usage is moderate and fluctuating, but continuous. Immediately prior to this I had completed a scenario and disbanded a few infantry units I wasn't using.

Screenshot as of bug:

Files

Error in mekhqlog, but I'm not certain if it has anything to do with the issue. Didn't see anything in megameklog.

Will edit to add campaign save file and reproduction steps if I can get it to reproduce after force-quitting. Annoyingly, I don't have a save immediately prior to the error - might have to redo the scenario as well.

Okay, loading from the save and trying to Mass Repair before completing the scenario had no issues, but after completing the scenario again (and saving before testing further) I can now consistently reproduce the issue. Not sure why it changed exactly, but debug tools should tell you more.

Save:
Coppercoats.cpnx.gz
No custom units.

Reproduction steps:

1. Load campaign file
2. Navigate to Repair Bay and open Mass Repair/Salvage menu
3. Click Select Active Units
4. Click Start Mass Repair/Salvage

The infinite loop is in the conversion from LRM 15 ammo to LRM 5 ammo. The warehouse has enough shots but the load bin routine believes there is not enough. Investigating the correct fix now.
