Lichess, please fix this

If you put in an illegal pgn (with illegal moves I mean) into analysis board or studies using the field where you ender the pgn, it allows you to do that and results in trippy things such as the study above, where I entered
"1. e4 e5 2. Ke2 Ke7 3. Ke3 Ke6 4. Kd4 exd4
5. a3 Kd5 6. exd5 a6"

It worked, but it's not supposed to do so.

Someone was able to put pawns on the back rank with the same idea lol

@WallaceTwo I just did that too.

hmm... that is odd

@A_0123456
Well, an illegal position can be analysed and the Stockfish evaluation is very odd in that case and I have tried it some times.
But no illegal moves can be played, I tried after you said so! So, I don't know why it happened in your case. Or did you set it to antichess variant the first chapter.

@Akbar2thegreat No, just go to the pgn box in the study and type in 1. e4 e5 2. Ke2 Ke7 3. Ke3 Ke6 4. Kd4 exd4
5. a3 Kd5 6. exd5 a6. No need to even set it to Antichess. And besides, the computer would analyze it if it was antichess. It happens consistently.

@A_0123456
Will check, but even in antichess the 5th move would be illegal since if a piece can be captured it should be but Black played Kd5 instead of Bxa3.

Or you could just enter valid PGNs lol.

#8 it's just hilariously broken...

Well, it's not exactly broken... it's just that it's breakable if you go out of your way to screw it up.

I'm sure Thibs has more important bugs to deal with.
