Broken arrow transfer

[fredingue]

I had 2 crashes about the same issue : i can give Lydia armor and weapons, but when i share my shack of iron arrows the game breaks

Nota : the iron arrows are those used (with arrow pointing them in the inventory). If i use other arrows and give her the whole iron ones, it does not crash.

I have had the same issue, so it's not just you. But I think I know why, I believe followers already have an infinite supply of iron arrows (as they always shoot without having a bow and arrow in their inventory)
So, while other arrows and bows upgrade her default, I think she a 'clean sheet bow' with iron arrows infinite, and when you try to give her another 'clean bow' or iron arrow, the game crashes.

Just my two cents. Just remember not to give Lydia iron arrows and everything will be fine.

It seems the game only crashes if you give her _more than half_ of your iron arrows. If you have 100, and give her 51, the game CTDs. If you give only 50, no crash. If you have 300, you can give 150, but on 151 the game crashes. Very weird.

I use the Ultimate Follower Overhaul, which might affect this. Haven't yet tested without it or without any mods.

Actually, now I tested some more, and could give her 51 out of 100 arrows. Also from all of my 341 iron arrows I could give her all but 24 left for me. So out of those, I could give her 0 to 170 arrows, or 317 to 341 arrows. But not any amount between 171 to 316.

Also, first I thought that if I gave her just one successfully, after that I could give any amount. But that doesn't work either.

Furthermore, if I put a very large amount of those arrows to a barrel, I couldn't take them back any more, even with Take All. I believe this is related. I couldn't yet determine the amount which would trigger this bug.

I believe this is some kind of small integer overflow, but I cannot yet determine how exactly, because the amounts are not directly related to amounts of 256 or 128.

Anyway, it seems it is safe to give Lydia iron arrows, if you just give her less than half of yours all the time. But as weird this bug is, I cannot be sure.
