Seirawan Chess variant error

as on the title we will talk about the variant error Seirawan Chess

A game error is that when a player joins the game and plays, it will happen that he places a chancellor or archbishop, when the opponent moves and moves, that piece will return to its original position.

In other custom test variants with Seirawan Setup rules, the player's time to place a piece is taken into account by negative numbers.

and of course it's an error

i can't seem to place down anything

also why there is literally no variant explanation

but now it's fixed
