AI Bots cluing about the "rainbow" colour in rainbow mode

I'm not sure if you can look at the logs from the game URL, but here it is just in case: https://hanabi.cards/CleanDuckMaroon

In two cases, the AI gave an illegal clue of "rainbow".

The first time, it gave it to me. One of my cards was a rainbow card, but it marked the rest of my cards as having no colour in the deductions.

The second time, it gave the "rainbow" clue to another AI. All of its cards had the colour deduction set to "rainbow", even for non-rainbow cards. This caused the receiving AI to play an incorrect card.
