The external model issue is from the livery not being updated to use the current new 3D model. If you get your liveries from the iniManager, it should just need to be updated there. Otherwise, if you get the liveries from other sources, you might need to wait for the livery author to update the livery with the new model mapping. As for the load time, it's always like that when you jump into the aircraft the first time after every update. This is because the sim needs to re-cache the aircraft files again for any new version. This would only occur for the first load. Any subsequent load into the aircraft should be quicker as usual. So, even if you rollback to 1.0.3, the first time you're trying to load the aircraft would take 15 minutes as well. You just have to be patient grab some snacks, or make some coffee and let the sim do its thing and once it's done caching, you should be good to go.

I would just choose to Restart Couatl option. Or if it doesn't appear for you, just ALT+TAB back to your Windows desktop, and disable Couatl manually from your system tray, and open Couatl again, and that should reset.

Your number 1 SimBrief Profile is the "Default" profile for the iniBuilds A350 that's stored in the SimBrief Database. Your number 2 SimBrief Profile is the profile that you have saved in your account. Basically, when you create a new airframe to be saved into your account, you would take the default profile from the database (number 1) and you save it into a new entry as profile number 2. So, any additional edits that you do in that airframe, like default CI, or fuel profile, etc will be saved to your number 2 profile. Number 1 profile will never change as that's from the database itself. So go for number 2 if you already tweaked it to your liking. Do we really need different profiles for long/short sharklets? I mean, you can customise the sharklets in the sim anytime anyway, I would think a single profile to cover both variants should be enough. We already have a separate A359 and A35K anyway, and I think that's enough for our needs. Otherwise, if you want a different profile, then feel free to create a new airframe again and do your own tweaks and save it as your "short/long" sharklets.

I think it has something to do with the "Back on Track - You Crashed" function in the MSFS 2024 itself. You may have got it while taxiing. But I had the same thing happened to me while I'm stationary and parked at the gate, with engines off, and about to do my deboarding. Here's a video evidence.

Your copilot avatar is tied to your MSFS 2024 Profile. Not the Aircraft OIS. To remove the copilot. Go to your FS24 Main Menu, and open your Gamer Profile on the top right, and there's an option for the Avatar, just open the Copilot and set it to empty/none. Then it should also remove the copilot from all your aircraft. But for this one, I agree. The v1.0.4 is finally looking good with the copilot avatar visible in the -900 variant. But the -1000 is in the wrong position. I'm assuming it's using the -900 position value of the copilot on the -1000, so they spawn further back due to the -1000 has longer fuselage. If this can be fixed in the next version, it would be great. Otherwise, I might need to create a separate mod for that.
