It's all packaged into .dat now.
If you want to customize party.txt, you can either extract it from rpu.dat, or download it from the repo (this is the same file). Place into data/data, and edit it however you want.
Lastly, check out party level match component in FO2tweaks.

The rock must be present. Something is wrong in your installation, and I do not advise to proceeding with the game until you figure out what's that.
The logs must be in backup dir inside main game directory.

OK, I found and fixed the issues. One, as you noted, is a wrong setting check, the other was re-declaring a var. I didn't notice it because I usually play with knockback disabled. A new release is pushed. (And for the future reference, you can disable scripts in dats surgically by creating empty fil...

do you have a save?

The code in the linked post requires enabling unsafe scripting, though.
Also, I wonder if there's a way to disable it at all, and only play the animation on actual reload.

I'm not actually sure, but probably using projectile pid from misc.lst. Could also be just checking damage type. I remember back when I was first implementing fire damage for Molotov, it would stop exploding and become a "throwing weapon". Or could be both. Try opening and comparing various weapons ...

Just the two files mentioned in the linked topic, that seems to be enough.
And I don't install much, apart from testing. My main installation used for playthroughs is old.

What do you mean, "when"? What are you trying to do? For example, there's CombatDamage : Runs when: Game calculates how much damage each target will get. This includes primary target as well as all extras (explosions and bursts). This happens BEFORE the actual attack animation. AI decides whether it...
