I do believe I've encountered a bug!

This nasty thing occurred when handling an MFFS (Modular Force Field System) frequency card.
It appears your mod does not like the "<" and possibly the ">" symbols.
This was a mid-game crash.
Upon restarting the client this one happens:
java.lang.NullPointerException

Although it doesn't mention Status HUD, disabling the mod resolves it.
