Seriously, he needs to just start banning people who are suggesting somehow doing some magic split that will solve everybody's problems at once.
You guys aren't getting it. It's not sinking in. Interiors and Terrain are terrible. They haven't been improved in years. The developers lacks the time, effort, energy, and motivation to improve something that will not ultimately influence gameplay in the slightest.
We're using the same bedroom that has been around since v0002. That was 5 years ago. The framework in the engine that hosts the interiors and terrain was so poorly written that just by having it exist it causes problems with other aspects of the game. They are not going to keep it. Get over it.
