YOU SHOULD KNOW THESE BUGS

If you're jailed as pirate and an ambusher visits the same person you chose to duel, you will be attacked in jail by the ambusher and also see who they are.
Wow it's my own screenshot!! I had this happen to me and I think I ended up duelling the ambusher and winning, instead of outing them the next day.

When pirated, you are roleblocked. So, roles with roleblock-immunity should still be able to perform their night ability, however this bug slightly prevents that from happening.
If you have roleblock-immunity (necromancer, retributionist, escort, consort, coven leader, pestilence) when you are pirated, your visit will go through but your night ability will not.
Example: a pirated coven leader will visit their two targets but neither will be controlled.
Example: a pirated escort/consort will still visit their target but the target will not be roleblocked.
A lookout or tracker can see you visit, but nothing would have happened to your target(s).

As psychic, if you are controlled by a coven leader you will see the controlled message twice.
Similarly, if you are hypnotised with the controlled message as psychic, you will see the message twice.
This is good to know because psychics will assume they were both witched and hypnotised which is just not the case. Anyway, a good hypnotiser would avoid using the controlled message on town investigative, as coven leader steals the results so it would be obvious if you got hypnotised because you'd still have your results.

If you're saved by a trap, you may see the message that a bodyguard protected you instead.
This can cause confusion. An evil died to a trap, a bodyguard saved me so where's the person that the bodyguard killed? And why isn't the bodyguard dead? Then people will start believing there's silent doctors and that's a whole separate issue.

If you are controlled by a witch as retributionist, the corpse you used that night will not rot. Meaning you can use it again.
This can cause issues like coven leader being unable to kill a retributionist in a 1v1 because they have infinite doctor/crusader.
I miss the old retri :(

You are poisoned. The following morning you plead for a doctor to heal you. That night, you perform your night ability not knowing if it will be your last...
You were saved!
But... if you see the green message, a potion master healed you.
If you see the red message, a doctor healed you.
Now if there's ever a poisoner and you see the green message, you'll know there's a silent potion master too.

It's unknown if these two doctor related "issues" are bugs or meant to actually be in the game.
A doctor won't see that their target was attacked if their target was attacked by a bodyguard.
A doctor does not get a message if they cure someone of poison.

This obviously isn't a bug but it MIGHT AS WELL BE.

I found out about a lot of these bugs through literally reading every single page of the ToS wiki back in 2018-19. There's more I didn't include because I didn't think they were worthy. You can search for yourself. Every role page has a "trivia" section that lists active bugs.
I read somewhere that these bugs are known by the devs and they have taken a won't fix approach. So they're basically gameplay mechanics now :D
Anyway ty for reading, add me up in game - impapasmurf
