Prerequisites and Pre-Issue Checklist

  • I'm reporting the issue to the correct repository:

  • MegaMek

  • MegaMekLab

  • MekHQ

  • I've tested the issue against at least the latest MILESTONE version

  • I've asked on the MegaMek Discord about the error

  • I've reviewed the BattleTech rules and MegaMekLab documentation, and I've confirmed that something isn't working as intended.

  • I've searched the Github tracker and haven't found the issue listed

Severity *

High (Major Disruption): A major feature is broken or incorrect, but a workaround exists. Possibly the same issue as #1575 but I found it happening on canon units with repeatability.

Brief Description *

Something's going wrong with loading units that have Compact Heat Sinks. See Below

Steps to Reproduce

1 . Load the Bombard BMB-016
2. Note the Heat Sink readout displays Singles and Engine Free 4
2024-10-30_221245
3. Check the crits tab and note the 2 CHS in the CT:
2024-10-30_221322
4. Back on first tab, click the up arrow on the heaqt sink number. Exception occurs
2024-10-30_221450
5 . Back on crit tab, in CT:
2024-10-30_221646
6. Back on first tab, click up arrow again. Number goes to 12.
7. Crit tab, suddenly unallocated:
2024-10-30_221733

At this point you can switch back to CHS, set it to 10, and place the 2 CHS back in the CT to get back to how it was (supposed to have) loaded.

Operating System *

Linux

Java Version *

17.0.12

MegaMek Suite Version *

The log is very short so I'll just paste it here:
