Broken Arm challenge

[Thracos]

Does anyone know how to complete this? I have all the other first aid challenges done, but have not been able to splint a single broken arm. When my broken arm message pops up the arm instantly heals and I don't have time to fix it. as in the red arm flashes on the screen, but no counter comes up, then the red arm disappears. This seems like a bug, but if if there is a perk interfering with this can someone let me know so I can speck out of it.

Are you pretty sure you're splinting a broken (dark red) arm and not a sprained (reddish orange) arm?
They have the same debuff icon except the slight color difference, so it's easy to mix them up. A sprained arm will heal instantly if you have a point into medic (I think) before applying a splint or cast.

If that's not the situation, it definitely sounds buggy.

Do you have any perks or armors that are meant to heal your critical injuries faster? Because maybe they are calculating incorrectly and instantly healing the broken arm.

I got that too; thought I was done for when I accidentally strolled into a bunch of zombies and got my arm sprained and immediately broken. I hurried to open my inventory, to use my single splint and hopefully survive the first blood moon I had coming up. I didn't have points in anything but Strength. I couldn't apply the splint, and first I thought maybe I applied a splint but had had two, which would explain that I still had one in my inventory.

But when I looked at the character screen, my arm was fine.

I had meant to write something about it, but forgot until now.

I do have the fast healing perk under the Fortitude tree, so that might be where the bug is. I have had sprains in that I have ignored hoping it would become a break but no luck so far. Once it becomes a break it instantly heals, no cast or splint used.

I have the exact same problem (even without investing in healing factor perk). But I have observed that if you get hit by some very strong hit that instantly breaks your arm for 2h, it will stay. EG being hit by Zombie Bear or Dire Wolf could break my arm without it magically curing itself.
