Will progress be saved between platforms(ps4 and steam) because of the boundless account?

PS4 <==> PC Characters

Again - we’d happily remove the restriction. It’s a PlayStation requirement. Without the characters locked per platform we couldn’t have released a PS4 version supporting cross play. We concluded the number of players who wanted to play on both platforms was likely very small - so accepted the limitation to proceed.
