discovered some bugs:
in zea's quest for her shirt, we check the slums. in the slums, i saw an NPC running up on me, so i preemptively threw them down. zea's search ended while i was in the sex animation, and after the dialog completed i was removed from the sex interface. i was still locked into sex with the NPC, but i lost all abilities to interact with anything. there was no way to cancel sex.
when an inventory screen is active, you can exit it by hitting "esc" and selecting options. if you do this a few times, inventory breaks: the mouse cursor is lost, no items display in the inventory, and the only way to exit the inventory screen is to again hit ESC and select options. I had this happen while trying to manage an NPC's inventory, and the result was being stuck in the "hello" dialog screen (without the dialog interface,) with no way to interact with anything.
it seems like pregnancy can be overwritten by orgasm/ partner orgasm. unsure if this is merely visual or also tied to actual pregnancy stage, i'll pay closer attention to it next time it happens.
