I ran into a problem recently that brought my building grinding to a hault. I went over the brick limit and after doing some searching i found why. Now i think i might have a way to fix the problem. The problem is that if badspot were to increase the bits so we can have more bricks it would also increase load time, and if you go to over 1mill bricks like i intend to do the load time will be huge. To solve this my idea is to prompt the clients as they enter a server asking them if they would like to automatically save the bricks from the server to there computers for faster loading next time they join. Then as they play on the server and build, everything is saved to a file on there computer. Then when they leave, the server will keep a record of what changes while they are gone and then next time they join the server will only have to send them what has changed while they were gone. Though i do know this would put a load on the servers, i kinda mean this more as an idea for dedicated servers that should have the power to spare. To cut down on memory use maybe allow the server to clear data its holding for clients that have not joined for a set amount of time.
BTW badspot can you put the brick limit as high as you can like maybe a few million bricks or so. i mean i paid money for a game i could build in and now i cant build because there is a limit. dont forget computers are getting better and better every day and i can get over 100,000 bricks on screen at once with no lag on a slow old computer.
