Done End Bug

I don't know if post it here or in Git because is a server related issue. The problem is that when you try to enter the End by the Nether Portal, you can do it the first time but later you can't access it again. Here the error:

 

Try redoing the portal

 

Already tried, I even moved it to another place, another player tried using the portal, didn't worked he got the same error. Ghostriderrr told me that Chugga_fan knows how to fix it, he need enter into his portal or something like that.

 

Make a ticket and I will bring it to an admin.

 

The problem is, the end unloads once someone enters it for the first time using that nether portal, the fix? get someone with a warp to the end or make an end portal with gaia spirits and obsidian, which is intended

 

you need to be able to to get dragon hearts, so yes, you should be able to

 

And in single player, or at least when I played it on SP the End Portal was natural generated and the modpack has Garden of Glass, that mod makes you able to craft End Portal Frames.

 

Shouldn't spawn, @caithleen is it possible to fix that if it does spawn in SP?

 

Both ways to get to the end are currently viable. Maybe the vanilla fortresses will go away in beta
