@Andrewkm I have noticed that if you use a sponge on a portal that the water goes away, yet you are still able to use it! If we remove all water, that will eliminate all portal lag and stop people from dying under portals!!!!
Wait, really? The only problem i see with this is differentiation between portal and empty portal. Besides the obvious what in the name of logic made you try this xD
true... hmm. we'll wait for andrew based on the fact that you have already tried this, and on the off chance it causes issues/Andrew wants to remove it asap, I am going to take the risk of mentioning a god... @Andrewkm ... *shields eyes*
Doing this will break the portal after some time. (we did something similar by removing portal blocks a while ago)
Ok, since you said you deleted the portal block to find out, could you the "portal" block be torches or paintings or something like that?
I don't know. That might be possible. I do know that it doesn't have to be water because Ike and a few others built a lava portal
