Light Sources not producing Light

[Kalgert]

So, this week has been one problem after another on my end

So, here is how it started: I was on my High Elf who had a torch, it produced light just normally, then I noticed at some point that I didn't have any light from the Torch anymore, I assumed it expired or something so I carried on my way.

Then I noticed that my Fire Beetle Eye on a separate character didn't produce any light either. I checked also with buying a lantern with the same kind of result.

Checked on my Dwarf who has a light-producing helmet, same result as the High Elf and the Human.

So, here are the results on characters that I checked for light:

Paladin, has a Lightstone, no light
High Elf, has a Torch, no light
Monk, had a Fire Beetle Eye, now a Great Lantern, no light from either
Dwarf, has a Miner Cap, no light.

I don't think I've done anything to upset the light production for my characters, other than die a couple of times on my High Elf and buying a new Torch just to see where I was going as night came when looking for my corpse. It all started when I came to the city

Any ideas what may be the problem?
