Hello. After checking in with the greater dev team, we've confirmed that this bug was intentionally fixed due to the risk of it causing more serious issues with stadiums and gameplay. That said, while the community team can't make any guarantees, we've again passed along the feedback and the dev team is aware of the community's interest in adjusting foul territory in custom stadiums.
Just to clarify, this decision wasn't made by Joe specifically. Feedback is always welcomed and regularly shared with the dev team, but final decisions around priorities for bug fixes and feature requests are not made by one person from the community team. While venting frustrations and dissatisfaction about the game is allowed, we ask that it remains constructive. Personal attacks toward developers or other community members don't help move the conversation forward and will not be tolerated.
