Hey there! , it seem you have a ''Ticking entity'' with one of your ''Sligneris''!. dont panic! , i know how to fix it!.
1.Download and install NBTExplorer
2.Open it and go to your world that has the ''Ticking entity'' problem
3.Go to region
4.Go to each mca (if you have multiple) and find the exact cordinate/chunk of your ''Ticking entity'' (your cordinate is 0,-63 or check every chunk that has the cordinate) Ex: Chunk[10,1] in world at (0,-63)
5.after you find it open it and go to entries
6.Go to tileentities (if what causing the problem is mob,etc. go to entities)
7.check every entries (if you have multiple) and look for id name Ex: id:Sligneris
8.now delete the entries that has the ''Sligneris''
9.now save
Congratulation!. you just fixed your minecraft from ''Ticking entity''. now you can play the map again with no problem anymore. (dont place the ''Sligneris'' in where it got ticking entity problem or it will occur again!)
P.S i dont know what is sligneris
