[MHQ - 50.03 Nightly - CI1729] - Deploying Patrol lance created NPE - java.lang.IllegalArgumentException: Unknown Weight Class in getClassName(int)

[UlyssesSockdrawer]

Brief Description *

Apologies - only save file available is from after the error happened. I know this isn't super useful, shame on me for not saving in advance.

Campaign is in the Age of War, and an Artillery Base modifier is present, so I suspect there might be some kind of unit generation issued tied into FG3.

Issue occured when deploying the Patrol lance to the bottom left hex on the StratCon map.

NPE was triggered, with the following in the logs:

"22:21:26,560 ERROR [mekhq.MekHQ] {AWT-EventQueue-0}
mekhq.MekHQ.lambda$main$1(MekHQ.java:296) - Uncaught java.lang.IllegalArgumentException detected. Please open up an issue containing all logs, the game save file, and customs at https://github.com/MegaMek/megamek/issues . If Sentry is enabled, the error has also been logged.
java.lang.IllegalArgumentException: Unknown Weight Class in getClassName(int)
at megamek.common.EntityWeightClass.getClassName(EntityWeightClass.java:492)
at "

Log attached further down the report.

3. Steps to Reproduce

1. Go to Area of Operations tab once Patrol lance has returned.
2. Right click to deploy Patrol lance.
3. NPE triggered (hopefully).
4. 'Deployment' window remains open, but cannot click confirm. Must be closed via 'X' in top right.
5. Force appears to deploy correctly to the map and a scenario is generated.
