Drone taser attack crashes the latest hardmode/openxcom at least on linux; an attack sound is played, but then the colors get messed up and the game gets stuck. I submitted a report on github issue tracker. Because the issue tracker is otherwise empty, I wonder if it's supposed to be used. So at least a heads-up here as well. (Apparently I'm not allowed to post external links, so I mangled the URL: https ://github.com/hellrazor4223/hardmode-expansion/issues/2)
Here are the juicy bits from the gdb stack trace, but not sure if it helps:
