Minor If you take drugs as a critter the rainbow effect never stops.

[Skornzy]

Regardless on if the drugs are still in you character's system, the rainbow effect on the screen will still persist. It does seem to go back to normal only for a few seconds before starting the rainbow again. It's very annoying.

1. Be a critter (in my case a cat).
2. Take cat drug.
3. Permanent screen rainbow.
