Invalid glyph error when opening help with monochrome

[Smoogy]

I found the purple-on-black of some of the help menu hard to read, so I turned on Monochrome help. However, when opening either <4> Command Listing or <5> Adventuring in Incursion, I get an "Error: Encountered invalid glyph (glyph: 58969, id:1625) (those exact numbers are the crash from <5>, as that is the last one I had open).

Again, this only occurs if the Monochrome Help option is on, and ceases as soon as it is turned off. I've included the minidumps from crashing on each page.

Thanks. Great bug report. Looks like you've covered everything, will look into it next allotment of time I spend on Incursion development.
