Yes, it will stay in your save.

bumping this to spread awareness, im also getting lag from this problem

There are mods that fix this.

still a huge issue for console usersim just spreading awareness in general ill be making threads in the console sections when I have the time

Ya feel your pain console guys(and gals) but since of mods fixing it on PC the issue kind of died on the vine. The mods are very stable so I guess console people call them nonstop and ask for this fix being added to a patch. It is in the unofficial patch notes as well as the weapon drop bloat which affects you more I can assure you. These should be on your top list of things that console players should be asking for in a patch. Don't let them skip it because of unofficial patches and mods for PC. Forums are pretty worthless try more direct means of contacting them imo.

yeah I know your right ill keep going with my half a**ed crusade as best as I can, thank you for the info.I know its self explanatory but could you give me more details about the dropped weapon bloat, im assuming enemy weapons sometimes don't disappear (does this happen with most outdoor bandits or just random encounters or who/what exactly?

Sure thing as far as I understand it (Amegpo or another modder that makes these debloat addons could say for sure) what happens is when you kill someone with a weapon shield etc. EQUIPPED they have a chance and a pretty strong one to drop them and they will basically not clean up when the corpse does. This occurs anywhere inside or outdoors so the addons basically make it so when you were to walk over to the dropped item it would be like looting the corpse of whoever dropped it as opposed to picking it up. The ideal thing would be for you to be able to loot detached weapons and shields as intended without them remaining in the world upon corpse despawn. The mod I use just basically deletes them with the corpse. The default game method leads to a small amount of bloat but after lots of kills and not picking up worthless heavy weapons and shields you can see how this leads to a larger save file.

Thank you
you have been very informative. Now off I go on my crusade
ill get their attention somehow

No problemo....If you figure out how please let us know what you did.
