Ill update you if this works. Thanks for the tip!
UPDATE FOR 1.16.220
still no luck. Tried to connect in the latest patch, but locating server was all i saw. I thought I had come up with a solution, that the world was lagged out by redstone machines, as right before I got glitched I built a massive redstone light array. After my friend dismantled it, i still couldn’t join. If this info is needed, and if mods are still watching this post, the world is 55 Megabytes large and a couple years old. We use the Halo Mash-Up texture pack, and the area we were in was in a tundra that was heavily bombed by tnt and has a massive underground structure made of iron and redstone contraptions.
It also still doesn’t work in 1.16.210.
My friend finally found out the size, it is 55 Megabytes.
As of now, i’m still waiting on a response of the world’s size from my friend, but yes, it still does not work in 1.16.201.
IT WORKED!!! Thank you so much!
