I have set the rts to 999999 or more and the game couldn't "load" any blocks
I don't know if this counts as a glitch because I have seen his on other versions too
Video:
i might be wrong and this is not a glitch but when i loaded the world again after ending Minecraft on task manager the world loaded back
Don't set this directive to such insane high values. Things like this are to be expected with values that high.
