No idea if this is happening on Windows or not, but using Arch Linux and WINE 1.9.24, I'm getting a couple errors with .41 that I wasn't getting with .38 in the dungeon. Text in the "Reason for Imprisonment" column overruns boundaries (likely because of the column editing with one of the last updates on the 1024x768 interface) and when selling a slave, the text in the box seems to have been cut down to "the slave girl for xxxx gold", cutting off the first few words. Picture attached, as I don't know that a log would really be useful in this case. Again, might not even occur under Windows, but I can't check at the moment.
EDIT: Also, did I mess up my settings, or did pregnancy time get severely reduced? Seems to be 10/5 turns now instead of 40/20. Additionally, in confirming this, I noticed that using something like an Artificial Insemination Kit would inseminate a virgin, but the brothel management screen still just listed her pregnancy status as Vg.; while technically true I don't think that status should have priority.
