I'm kind of waiting for the singleplayer patch 1.12x or something to continue adding more stuff.
The OSP animations are already implemented (mostly) in my test version, and usually work.
Other than that, I've also made it possible to recruit town troops from the original defeated factions in towns you own, as some people have been complaining about the difficulty of starting your own kingdom and somebody else wanted mercenaries from defeated factions. Although it needs more testing. They'll show up and displace the regular mercenaries, if the faction is defeated and you own the town, or if you took over a town that the AI took first, the original faction still exists, and you're at peace with 10+ relation with them.
Multiplayer testing is always good. As I've mentioned before, I spent more time beating up bots than actually porting, since I did the items before the troops. The uniques are tossed in as a bonus, I've upped the amount of gold you can have (to 25000), otherwise you won't be able to afford uniques (which are ~15000) and armor at the same time.
About the death-cam and stuff, it appears that try_for_agents, which cycles through everybody on the battlefield, does not work as it did in the previous versions. So the camera won't lock on to anybody when you die, so we'll have to wait for the original coder to port it to Warband.
The prisoner escape bug should be from Native. It'll probably be fixed with the next patch. On the other hand, I've given the sneaking in better equipment (iron staff and darts instead of practice staff and throwing daggers), but the guards are now tougher. So have fun playing the next version, whenever it gets released with Silver Wolf's lods that I'll dig up from the other post.
I have no idea about the pickup bug. All the arrows and the nomad bow are defined for multiplayer. Are you playing as a respawned bot, or as an actual player class? Some of the bots have no weapon proficiency defined for weapons like bows, so it might crash? See if the error is replicable, or a one-off memory leak or something.
