Anyways glad thing work out alright now.
As
Teravisor pointed out, your saves are fine to use since the code and changes are updated on launch. That "Version outdated" is just a notification, unless there were some major changes to the code its perfectly safe. As for the damage calc, there were some issues in 0.4.2.3 but I kinda skipped over that version so I didn't really look into it much, especially since the 0.4.2.4 didn't have those problems. Translation files don't mess with the code, so at worst you could get an error or a crash. I proofread them multiple times, so they're ok to use. I'm happy everything works good now
Not sure about high tier weapon as my Lona is poor hobo.
Nearly all melee, one tile range weapons have the Sap property (that downed state). This includes basic normal unarmed attack and heavy assault attack, as some weapons don't have a heavy skill. Yes, pickaxe slow/more stamina damage/0.5 health damage. Besides increased stamina damage, mancatcher inflicts stun more often than other weapons (example: on basic skill mancatcher 10%, wooden club 7%, scythe/sword 1%), on mancatcher heavy skill its 20% to stun, also on control which attacks all adjacent tiles 20%. Mancatcher inflicts chest and head wounds often too, 15/25/15 % respectively.
So, besides Orkind and Fishkin, can Lona get knocked up by anything else that's not human (and if it is, where can I find it?)
All pregnancy events are as follows: Abomination (east of Doom Fortress), Fishkind, Goblins, Orkind(orcs, those big guys with goblins), Human and Moot. There is also the Deep One pregnancy counter, but no related event or baby, maybe it transfers to Fishkind, haven't tested it. Parasites from combat or urethral/rectal seedbed count as birthing also. Finally, there is the miscarriage event too, but I guess it doesn't count...I included it anyway.
