There's painfully little else I can tell you. All other abilities I have tested work fine, but night vision will not give me the buff. Shame, as NV and water breathing are a brilliant combination when playing with underground oceans.

Assuming invalid, haven't been able to reproduce this, and no other reports of this have come in.

I'll try removing mods, I guess. I'll report when I have found something.

Are you sure there's no other mod disabling that ability? Because I can not reproduce this.

I am having the same bug, so far all of my abilities work perfectly, but Night Vision doesn't.

I just tested if a Night Vision potions worked and it did.

@milano1110 Is the night vision effect active at all if you use the ability?

No, unlike fire resistance which shows up at the side of my inventory, the night vision ability doesn't activate at all

@milano1110 Can you reproduce it without any other mods installed?
If not, then another mod is probably blocking the potion effect.

Okay, I tested it and Night Vision works with only your mods installed. So that means there is a conflict with an other mod that prevents Night Vision from working.

So after testing, I found that apparently Inventory Pets is somehow conflicting and stopping Night Vision from working. After I took it out, the Night Vision started working again. I don't why that would be a conflict, but it was.

@milano1110 Can you report it to their issue tracker and reference this issue here?
