Have a look at Mesh Rigger ... a Skyrim utility but it works with Oblivion too (https://www.nexusmods.com/skyrim/mods/87672).

Vanilla archers always have one iron arrow in their inventory along with their leveled list arrows.

The trick with flags is to only use those that are absolutely needed (and the same goes for conditions).

In my experience none of the vanilla merchants open right on the hour ... some can be nearly an hour late.

Yes ... if your package is supposed to start at 6pm you see what package is running before it rolls past 6 and the check again right after the hour ticks over (or wait a minute or two in game time). If it changes to your package ID then you know something other than an AI package could be interfering (example a script). If it doesn't switch to your package ID you need to find what is stopping your package from triggering. For example I use conditions a lot and sometimes I have a brain cramp with them where it's my condition stopping the package from starting when that isn't what I intended under the current in game conditions. You can also examine the vanilla package they're executing before yours to see what conditions or flags it has set (example must complete). The game parses thru the listed packages from top to bottom each cycle, and if two packages have the same time then the upper one will always execute unless it fails any conditions that are set (then the lower one with the same time gets a chance). The system that Bethesda provided is powerful when well understood and implemented ... but it's also easy to shoot your own foot (get me to take off my shoes for you some time).

Something I use extensively while testing and troubleshooting AI packages is the console command getcurrentpackage. Open the console while the NPC is onscreen and click on them so that their refID is displayed. Type in the command and hit Enter and the ID of the package will be displayed. I generally get the package from before the time of the package I want them to execute and then once the time of my package has passed I issue the console command again. You can get the ID numbers of the vanilla packages and yours by double clicking the collapsed column just right of the first column in their AI packages list.

Blue's Engine Fixes is different than EngineBugFixes by Tiawar.

Have a look at Blue's Engine Fixes.

Try beginning the texture and normal map names with a letter rather than a number and see if it makes a difference.

It'It's not super recent but Bevilex' Mod list for Oblivion - Graphics might make a good starting place ( https://www.nexusmods.com/oblivion/mods/47591 ).

Just a guess as I don't play FO3 ... your cell has no pathgrid.

Something that may or may not be related .... some users of any skeleton.nif replacer that is based on later versions of Growlf's skeleton.nif (as found in Universal Skeleton NIF https://www.nexusmods.com/oblivion/mods/37596 and used as the base for killermonkey99's BBB Ragdoll Breast Physics - Growlfs Skeleton https://www.nexusmods.com/oblivion/mods/40739 for example) get the flying through the air on death part of the bug shown in the video. The part where they then bounce back apparently unharmed is different however.

+1 for JimboUK's idea ... neat and tidy by default with the option for actually utility when you want it!

For reporting a mod the Report Abuse button is right where it has always been ... below the About This Mod section and above the Requirements and Permissions and Credits drop downs. To report a mod comment the Report button is also right where it has always been ... top right corner of the comment you want to report. To report a Forum post you use the three dots ( ... ) at the top right to open the selection for either Report or Share that post (which is a change with the new Forum format).

Do you use EngineBugFixes (it has a fix for the stuck animation vanilla game bug). https://www.nexusmods.com/oblivion/mods/47085
