i'm trying to play with the custom board i made

So i used the custom settings to make a board and when i select what i need to to use it and it says "please use a valid FEN" after using the set up positions thing. and i have no idea if the fen breaks as i use it or if it's a long term bug?

If anyone has an idea please let me knowthis is what i'm trying to make

this is what pops up

as an fyi this is my fen code

rrrrkrrr/rrrrrrrr/rrrrrrrr/8/8/RRRRRRRR/RQQQQQQR/RQNPKNQR w - - 0 1

Ah ill try it in a bit because I need to keep my yt channel alive

Ok so apparently capitalizing makes it white and lowercasing makes it black

did it end up working?

No sadly it didn't work bece both have to have two colors in it and not an immediate checkmate

just you
