Pretty self-explanatory I want the mirror to be a mirror. No limits in mirror world that the over worlds would not have. Also, please back port to 1.12.2 since pixelmon is still there.

No problem also AWESOME this mod is the bees knees :D

?
So what is your request. What limits??
Also 1.12.2 is available.

It says on website that "Overworld Mirror is almost the same as the overworld but with less chunke size"

I want it to have the same chunks limit as the real overworld.

Well that info is outdated. Curseforge is the better source for information right now.
Thanks for reminding me. Need to update the website eventually.
