Do you have an estimate on how large % of users are getting this error?
If more than 10% I would suggest removing the detail box from that menu, or placing a non-clickable layer on top of it, to prevent frustration and bad rep. Because inspecting units before recruiting is something that all new users are going to do.
So far Ive seen reports of Win 7 and Win 10 gerting this CTD.
This only happens to me from the Build Screen with HRE Cuirassiers which happen to be Model 157 ( could 1157 be a typo?) I have saves and report if you'd like them but the image shows most of the information
