Today I have noticed that the Commando armor with +3 Carry limit, such as https://imgur.com/a/9Kqzd gives +4 carry limit when equipped, allowing you to have 6 nades to use on a single survivor.
I narrowed the possibilities down to the following:
1. It's not a bug, cause of morale: Item gives +3 carry limit, morale adds 25% to that, adding 0.75 carry limit, which rounds up to 1, adding +4 carry limit total.
2. It's a visual bug, the item should say +4 carry limit, but for some reason the line of text was written as +3 and then never updated again.
3. It's an actual bug and it should not give +4 carry limit, but +3.
I would like to know if it's actually a bug or if it's okay to use that 4th carry limit nade.
