Darkness/Ultravision bug

[wilkins1952]

To Reproduce

• Cast Ultravision/Darkness
• Ensure that Ultravision runs out while under the effects of Darkness.
• When Darkness runs out in this situation all players/NPCs will remain invisibile until the game is restarted

Specifics

• OS All OS
• Game build All builds
• Distro platform Steam
• Content overrides? Happens in all known Haks and Base game
• Regression? Broken from EE release AFAIK

If needed, describe the bug

The game does not correctly remove the Darkness effect from the player rendering them still unable to see NPCs/PCs unless they get within the usual range of Invis revealing, Only a relog fixes this.

If warranted, add videos/screenshots to showcase the issue.

There's a few...interesting interactions between Invisibility, Blindness and perception. Darkness uses a special type of invisibility and blindness. So fun.

There is no way to detect any Darkness effects that have been bugged by Ultravision being lost during the effect of darkness, even removing all effects will not remove this bugged Darkness.

The bugged darkness effect will still end correctly if it is changed to temporary, as it's set to permanent in base scripts. Another short term solution that modules can use is to apply Ultravision briefly on Darkness' exit script, as reapplying Ultravision clears the bug.

Here is a test module with a script setup to trigger and clear it: darkness_test.zip
