Teleport command causing glitches in latest forge 1.14.3 build (27.0.51)

[CykaBlyat]

Whenever I attempt to use the teleport command, upon arrival things around me act strange. I could not pick up dropped items, animals did not move (could not mount my horse, either), and blocks that require something to be underneath (like snow) were not destroyed when the block underneath was removed. I do have mods installed but none have anything to do with teleporting or anything remotely similar, except for Xaero's World Map and Minimap mods, which worked properly (alongside the teleport command) on previous forge 1.14.3 builds.

 

Hopefully I'm not the only who experiences this bug, just figured I'd make an account to report my experiences.

All this just sounds like a lot of lag. Can you please post your log?

Here is the log from when I entered the single-player world onwards:

The teleport command functions properly and there are no issues if I go short distances, but when I use it to go long distances, the aforementioned bug (permanent lag, I guess you could call it) occurs. If I teleport over a long distance, the area that I teleport to loads properly, but I have found that it loads only a few chunks and then stops (If I recall correctly, it loaded approximately the same number of chunks both times I tested it). If I go into the void, my player never returns to the world and I am stuck there in free-fall until I close the application (attempting to go to the main menu gets me stuck at a "Saving world" screen. I have also had that occur a few times randomly upon death in other worlds, such that respawning and going to the main menu does not work.)

 

Hopefully the log is sufficient, I assumed that anything that occurs in the bootup process of Minecraft that is logged is not relevant (I could be wrong of course, and if so I can provide the full log upon request.)

Also, I noticed that the ender compass mod was mentioned in that log, but I just tested this once more without that mod and the same bug occurs

It's strange, I've been testing teleportation to other far locations and it all works just fine but that one location where I've kept my horse causes the lag...
