Haven't used any custom LBM or SHP files. Also, no special characters in unit info or elsewhere. However, the custom OOB was created on 8.0 and then used as is in 9.1, if that makes a difference. (Some LBMs no longer depicted the same unit as they did in 8.0, so changed those as I noticed the discrepancies.)

After restoring the deafult OOBs and loading a campaign from the end of a battle (thus getting the upgrade screen), I could not reproduce a crash at all.

I then reloaded the offending OOB and did get the crash something like 1 time out of 3 tries, however couldn't pin down exact steps to reproduce. Changing units and scrolling the various unit lists were involved, though.

So yeah, the custom OOB is the culprit, maybe it can be fixed...
