An Xbox One version of the free-to-play game Happy Wars was made available to download publicly by accident earlier this morning, and players who have downloaded and installed this build will find that it has broken the Xbox 360 version of the game.
Developer Toylogic admitted to the early release of the Xbox One Happy Wars build in a Facebook post today. It stated:
" Please note that after playing Happy Wars for Xbox One, the current version of Happy Wars for Xbox 360 will no longer be playable. Official release of Happy Wars for Xbox One is planned in the near future, so please refrain from installing and running Happy Wars for Xbox One until that time."
"The issue of Happy Wars for Xbox 360 becoming unplayable will be resolved by the next title update of Happy Wars for Xbox 360. However, if you have already installed and played Happy Wars for Xbox One, we sincerely apologise for the inconvenience this has caused you."
Toylogic has not offered any specific information on how the Xbox One version would break the Xbox 360 version. The fantasy-themed RPG Happy Wars was first released for the Xbox 360 in 2012 and was the consoles's first free-to-play multiplayer game. The final Xbox One version should have cross-platform support for the older Xbox 360 version.
